Nelsonic Simon Game Watch simulator

 Hi folks, just wanted to post about a WWG simulator that Garrick of has made an online simulator of the Nelsonic Simon game watch! He made this after i have sold him mine since the one he had died out. 

And now, everyone can enjoy playing this very rare Nelsonic game watch. Fun fact: The Simon game was invented by Mr.Ralph H. Baer, which he also made the Magnavox Odyssey (now celebrating it's 50th anniversary!).

To play, go here: Simon Game Watch Simulator. Have fun folks! :)

 P.S. : I forgot to mentioned that the time which is displayed is the one in New Zealand, so now you know which time it is over there. ;)

The Microcomputer Mahjong (マイコン麻雀)

 Hi folks! It's been quite a time i haven't posted anything, especially since i'm in the mist of selling about 75% of my personal video game collection. The most obscure and exotic game consoles have now been sold but still have a few ones left but this is not the subject (selling the collection) but rather about an very obscure game console called the "Microcomputer Mahjong" or in Japanese "マイコン麻雀".

This was only sold in Japan in 1982 and was distributed by Japan Mail Service which you had to buy by mail order. The cost of this console was 48,000 Yens (which is now about $360.00 USD as August 2022 - heck that wasn't cheap back then) and there is two two different colored casing: The fist one (showned above) is the white model which has the inscription "マイコン麻雀" on the left corner-top on the console and with three drawing of Mahjong pieces and the other model (the grey), which is just plain grey with a black lining:

At the price it was selling (back then in 1982) and the distribution (mail order only), no wonder this game console is very obscure! There is almost "NO" information regarding the Microcomputer Mahjong so it was a challenge and took at least 15 years to gather all the information i am posting here. I finally discovered that not only there is two different colored casing but also the white edition was sold in November 1982 and the grey edition was sold in December 1982....some of you must be saying when reading this: "What the F%$? ?!" Yes, both models were sold one month apart! 

Check out these scans of the magazine "All Mahjong Feature" of November 1982:

(Cover of the magazine)

(the November 1982 ad - white version)

And here is the mail-order form which is in the back of the ad (inside the magazine) with a description and some specification of the game console.

Then, just one month later in the magazine "Special Selection Mahjong" of December 1982, it is the grey version:

(Cover of the magazine)

(The ad of the grey version)

And the mail-order form which again, is also on the back of the ad inside the magazine.

 Since i just know a few Japanese words, don't ask me what is written on the ads and mail-order forms as i'm not influent in Japanese and will eventually OCR these scans to try to translate. 

Here's a video (not mine) of the Microcomputer Mahjong in action:

As i've said, not much information regarding this game console but before i've sold mine, here's some few pictures:

The inscription on the left is "Power On/Off" and on the right is "Power input".

The inscription on the left ..ah! no need to translate ;P, the one in the middle is "Monitor output" (composite video out) and the one on the right is "TV output" (RF out).

And the power supply which is 6 volts DC at 1 amp and has a negative tip.

And here's a look inside (yup...the guts!) of the game console:

So this game console runs on a Z80 CPU and has 1k of RAM and 1k of VRAM. The main program is 16K and the graphics is 2K. Here's the list of all the major parts:

IC1 = 74LS166N
IC2 = MSM2716AS (graphics ROM)
IC3 & IC4 = MSM2114L3RS (RAM)
IC5 = 74LS245P
IC6 = N/C
IC7 to IC10 = M5L2732K (program ROM)
IC11 = 74LS20P
IC12 = SN74393N
IC13 to IC15 = 74LS157P
IC16 = 74LS138P
IC17 = Z80A (CPU)
IC18 & IC19 = MSM2114L3RS (RAM)
IC20 =  74LS02P
IC21 = 74LS00P
IC22 = 74LS75P
IC23 = 74LS367AP

There is al lot of TTL chips! And before i've departed of my Microcomputer Mahjong, i dumped the EPROMS to preserve them and especially, to be able to play with the "eMuCom Mahjong" emulator done by Hiroaki Goto aka GORRY. He made an emulator of this very rare and obscure game console but it doesn't include the dump of the EPROMS because of copyrights in Japan.

You can get the emulator with the roms and ready to play here:

I also included a (rough) translated instruction on how to use the emulator as originally the instruction were only in Japanese. So hope that this was very informal and helpful.

So until the next post, take care folks! =)

Hi folks!

I have updated the Chip-8 Database ( which is on with new games and demos for Chip-8, Super Chip, XO-Chip, ect. as the last update was in January 26, 2021.

I also uploaded a big file called "Chip8-to-type" which is about 300 Megs in size which contains all the "Non-Typed" games/programs that i could find over the years and that's more than 200 which need to be typed and preserved. Also included in the ZIP file is Martijn Wenting (Revival Studios) "Hex Coder" program to help out typing.

For the list of the "Non-Typed", please check the Chip-8 Archive List (April-01-2022).xlsx under the section "Chip-8 Games" that are in orange color.

The story behind the first Colecovision adult games (BUSTin-Out series)

 Hi folks,

Last night i was doing some cleaning on one of my hard drives and found an old text that Daniel Bienvenu (now aka Amy Marie "Purple" Bienvenu) sent me on December 12, 2000 (yup, 21 years ago) about a cheat code for any BUSTin-Out games...Holy crap! Completely forgot about this! But right after, a flooding of memories when Daniel, Marcel Thériault and me were having discussions about doing an adult game for the Colecovision on Yahoo Messenger.

So many (good and stupid) ideas came out of these conversations until Marcel send us (Dan & me) some pictures of one of his girl friends (Julie) and that what inspired us to make the very first adult game for the Colecovision! (Thanks Julie for inspired us).

 So Daniel started coding to see if the pictures would display on the Colecovision (remember, it was 2000 and not so many tools existed and Daniel all made his own tools!). We took black & white pictures as these took less space than a color pictures. Daniel was the coder and i helped with finding pictures that could look good with the help of one of his tools (CVPHOTO and CVPHOTOC). The first "ROMS" were actually pictures of Julie and some Playmates and until version 0.4, these Roms were unplayable as we couldn't move the paddle since it was just to see how the pictures were displaying (too bright or too dark or too pixelised).

As you can see, some are too dark, too bright or some too pixelised. If we had the tools that exists now, things would have been much different but that was then, we did what we could. But for 2000, this was indeed a great effort. 

We didn't wanted to do a porn game or anything explicit or smutty, just something exotic/erotic like the magazine Playboy. But since the screen of the Colecovision was only 256 x 192 pixels, that didn't leave to much details so we took only women which we could see from the head to their belly-buttons so that left seeing their natural busts (now you know why it's called "BUSTin-Out") ;)

What i don't remember is how many Volume 1 we made & sold but it sure wasn't a 100 copies. Here's the original cover for Volume 1:

 And this was the cartridge label for Volume 1:

But since we couldn't fit many pictures into a cartridge, Dan had the idea of making a serie of volumes and put a reference dubbed "collect'em all!" which he took from the Pokemons (catch'em all), so after making volume 1, Volume 2 came out right after:

And as for Volume 3, i don't ever remember doing a cover for this edition and i have no picture(s) in my database, but at least i do have the cartridge label:

 All cartridges, boxes (VHS), covers were either made by us to sell to members of the C.C.J.V.Q. or was made and sold by John Dondzilla for the rest of North America/Worldwide. At one of the C.C.J.V.Q. meeting (March 24, 2001), Dan & me we signed a couple of BUSTin-Out while having fun (and goofing around):

In case some of you didn't know, Dac-Man was Daniel very first game published!

And no...Dan didn't pinch my ass if it's what you're thinking...just me goofing. ;P

So if anyone of you has a copy signed by both of us, these are the rarest ones.

But that's not all, we even wanted to make a newer series called "Super BUSTin-Out" which instead figuring real women, we were going to use Hentai-type (but nothing smutty) girls from the waist up and in color this time. But with the poor success we had with the previous serie, we just did two different labels. The first is a Pre-Super BUSTin-out featuring a girl in bikini:

 But this was done before we wanted to use cartoon girls and if you did read the label, it states "(BUSTin-Out Volume #3)" which was also before we made the other Volume 3 label. So this label is a sort of in between projects (Volume 3 & Super BUST-in Out). After this label, this was the one we were going to use for the first Super BUSTin-Out:

 And again, still states "(BUSTin-Out Volume #3)" as we were not sure if we were going to release Volume 3 or Super BUSTin-Out !! There is a ROM of Super BUSTin-Out that exists but it's only a demo of the title screen:

 Click "HERE" to download the ROM.

After this project, Dan & me worked on another game and that one was a hell of a success. Just a hint: it's the non-official sequel of Space Fury. ;) I think Daniel released the ROMS not long after when we "retired" the BUSTin-Out project. He released Volume 1 to 3 and also a Volume 0.5. 

A couple of years later, someone at CollectorVision asked Dan if they could re-release all three volumes of BUSTin-Out and redone the covers:

And i would bet this was the guy who asked to do these re-editions:

 I'll give you some hints: this was his first C.C.J.V.Q. meeting on November 10, 2001 and has been a long time partner (still is) of CollectorVision and is the owner of the only prototype "Energy Quiz". Can you guess his name ? ;)

So if anyone of you want's a copy (or all three) of BUSTin-Out, then i invite you to buy them on the site of CollectorVision. Oh and almost forgot! The cheat code for any BUSTin-Out ROMS (Volume 0.5, 1, 2 or 3) - (original French text from Daniel):

Truc pour voir toutes les pitounes
dans BUSTin-Out Volume #1 et #2:

Quand tu démarre le jeu. Tu vois la fille, tu entends le son de mon logo.
Tiens la touche correspondant à # (ou * si tu utilise VirtualColeco) jusqu'à ce
que tu entendes un bruit après que la musique soit terminée.

Au menu, tu fais 5 pour enter dans le mode de visualisation.

Ça marche pour tous les BUSTin-Out ce truc là... et c'est le seul truc!

And here's the English translated text:

Trick to see all the girls
in BUSTin-Out Volume #1 and #2:

When you start the game, You see the girl, you hear the sound of my logo.
Hold the key corresponding to # (or * if you are using VirtualColeco) until
that you hear a noise after the music is over.

On the menu, you press 5 to enter the viewing mode.

It works for all the BUSTin-Out that's out there... and that's the only code!

So hope you have like the story and have fun folks! :)

The "Beyond" Game Module for the Colecovision

 Hi folks!

I finally revealed what was the "Beyond" Game Module project i was working on since end of May 2021. But this project is way much older as between 15 - 20 years ago, i had a discussion with Daniel Bienvenu (now AKA Amy Purple) that it was real easy to connect a game console (say...the Intellivision) to the expansion port of the Colecovision or any device that has an A/V output. I don't remember much of the conversation but that still "stucked" in my head since then.

Now past May (2021), the idea resurfaced so went to get all my old schematics, datas, etc. and began to make the "AV-to-CV" adapter. After an hour, it was finished. So a couple of days later, i tested it with a Jakks TV P&P Ms.Pac-Man:

Sorry for the hand, just blocking the "AV-to-CV" adapter (for now). And right after that, i've tried out a Famicom clone (or aka Famiclone) with the Pac-Land cartridge:

Took those pictures on May 31, 2021. So the AV-to-CV adapter works! But with this, you can plug any game console or device with AV output (DVD player, Camera, etc..). After that, i was thinking...could this be really useful ??!? Huummmm....good question. So i've put this aside until November, when i saw someone by the name of Robb Alvey on the FB Colecovision Lunatics group, which he has posted Retropie images called the CVPie...wait....why not use a real PI and plug it in the CV expansion port ? OK i know...why do this when you can use it as a standalone device ? Well first, you can play Megacart games and SGM (Super Game Module) games with the CoolCV emulator by Oscar Toledo (aka Nanochess). I've always wanted to buy one of these SGM but the last time, they sold like hot cupcakes on the fly and buying one on UPAY...are you nuts ??? Some sellers are asking over $800!! Really!! I'm not a money-tree damnit!! So have to wait for the next batch of SGM (if any will be made). 

But Robb gave me an idea...a great idea in fact! Plugging an actual PI on the CV so i could play Colecivision games (even if i have an Atarimax Ultimate SD cart) but also SGM games (and even ADAM games too). But...why stop there ? A Pi with EmulationStation (let's call it by it's all-well known name: Retropie!) can emulate so many game consoles and systems! And not only that...Arcade games, old computer games, electronics games...etc!! So was born the "Beyond Game Module" to speak because at first i wanted to call it the Ultimate Game Module but "Ultimate" was already used for the Atarimax cart and also the Colecovision Flashback conversion kit (The Ultimate Colecovision Flashback). The next name was "Infinite Game Module" but after rethinking of it...can't ever be infinite because of space on a Micro SD card or USB scratch that name. 

But if you ever saw one of the Disney Toy Story movies, the you must know the catch phrase of Buzz Lightyear "to infinite and...beyond!".....beyond ? Beyond!! That's it! Playing new games and game consoles, etc... is expanding "beyond" what the Colecovision can do. So i finally found the name of my new game module: the Beyond Game Module!

So on December 4th, 2021, i reveal the first pictures of the Beyond Game Module on FB Colecovision Lunatics group: 

And after a few days, here's the final splash screen of the Beyond Game Module:

I was going to show it off January 1st, 2022 but since i cought the ?&?**$@ Omnicron virus, had to wait another 5 days so now, January 5th, i have finally shown the Beyond Game Module. Here's the video of the BGM when i plug it and boot it on a Colecovision:

And here's a video showing which games systems and electronics games i've put on the Micro SD card: 

As for now since it's still a work in progress, i can play these:

* Colecovision Games with Megacart & SGM games (& also ADAM games)

* Sega SG-1000 Games

* Atari 2600 games

* MSX & MSX2 games

* TI99/4A Games with Speech Synth.

* Many Classic Handheld games (like Coleco Pac-Man tabletop)

* Entex Adventurevision games 

* Entex Select-A-Game (all 6 games)

* Arcade games (about 185 Golden age games- the best ones!)

* Löve (my OdySim - need to modify it to make it work)

* Arcade hacks (like Donkey Kong Xmas and Halloween)

* Vectrex games

* And also Atari 7800, NES and SMS games.

I will eventually put more like Intellivision, Magnavox Odyssey2, Bally Astrocade, Channel F, Game Boy, etc. Always dreamed to expand the CV and now this has come true (and for less than $100!!). ;)

Here's some more pics: 

The next post will be how to make your own PI-to-CV connector (schematics, part list, etc), which is simply the AV-to-CV adapter. This will be my gift to all Colecovision fans to celebrate the 40th anniversary! 

Until next folks, take care and have fun! =)
