Seems that i don't have much the time as i had hoped to make new or update simulators or even talk about a certain game console/system but i'm still alive and kicking.
In the meantime, here's a few comments and replies:

Legal eu tentei colocar este sistema no hyperspin mas tinha esse problema agora vou poder fazer isso.
In English: Cool I tried to put this system in hyperspin but had this problem will now be able to do it.My reply to Dennis: "Desculpem a nova atualização para o Entex Gameroom Tele-Pong, eu sou tão ocupado que eu não tenho tempo para nada, exceto respirar (LOL!). Quando eu vou ter algum tempo livre, certifique-i irá atualizar este simulador. =)".
In English: "Sorry for the new update for the Entex Gameroom Tele-Pong, i am so busy that i do not have time for anything except breathing (LOL!). When i will have some spare time, be sure i will update this simulator. =)".

For the record, the version of DOS in ROM here is DOS 3.22. (somehow managed to catch an int 21h ah=30h call in the MAME debugger)
My reply to Wack0: Thanks very much for this information Wack0, i thought it was a higher version like 5.0 or 6.0. this info will come very handy to anyone who wants to port DOS game for the VIS MD-2500.
BTW, is that you who posted this image on the MAME forum ?
An actual screenshot from MAME!! Cooooollll!!! =)
