Driver for the Entex Adventure Vision
|
||||
Entex Adventure Vision, tabletop video game console
|
||||
|
||||
Hardware notes:
|
||||
- INS8048-11 @ 11MHz (1KB internal ROM)
|
||||
- COP411 for the sound, 1-bit speaker with volume control
|
||||
- 4KB EPROM socket
|
||||
- 1KB external RAM (2*MM2114N)
|
||||
- 40 small rectangular red LEDs, a motor with a fast spinning mirror gives the
|
||||
illusion of a 150*40 screen (similar to Nintendo Virtual Boy)
|
||||
- 4-way joystick, 8 buttons (other than having buttons 2/4 swapped, left and
|
||||
right button panels are electronically the same)
|
||||
|
||||
The mirror is faked in MAME. On the real thing, the picture is not as stable.
|
||||
|
||||
A game cartridge is basically an EPROM chip wearing a jacket, there is no
|
||||
dedicated cartridge slot as is common on other consoles. Only 4 games were
|
||||
released in total.
|
||||
|
||||
TODO:
|
||||
- convert to discrete sound
|
||||
- screen pincushion distortion
|
||||
- EA banking is ugly, it can be turd-polished but the real issue is in mcs48
|
||||
- display refresh is actually 15Hz, but doing that will make MAME very sluggish
|
||||
- Do the spinning mirror simulation differently? Right now it relies on the BIOS
|
||||
specifying a width of 150, and the official games work fine. But it should be
|
||||
possible to update the leds at a different rate. In fact, the homebrew demo
|
||||
Code Red doesn't use the BIOS for it, and runs at 50*40.
