Nice to see a new Intellivision emulator. I tested it on Windows 7 and have some comments.
It runs too fast. It’s about 15% fast which is a lot.
Reset/restart crashes retroarch.
The sound chip sounds more like an a-y-3-8910 than an a-y-3-8914. There’s a subtle difference between the two and only affects some sounds. It’s a minor issue as it makes it sound like an Intellivision II rather than the original Intellivision.
Some games like Night Stalker and Tron Deadly Discs use the keypad rather than the side buttons. No way to map game controller buttons directly to emulator keypad buttons.
Analog control seems off by about 18deg ccw. I could not get north to work on one of my game controllers.
Keypad 0 and clear are mixed up.
Scrolling sometimes has some artifacts.
Auto Racing graphics are completely wrong affecting gameplay.
Dreadnaught Factor dreadnaught explosions are missing the solid screen colour effects.
Collisions in Bump’n’jump seem stronger than normal.
NASL Soccer has odd ball movements, ball often jumps back to the player.
Safecracker has no car graphics.
As in the video, Coleco Donkey Kong can’t pick up the hammer.
DK Arcade works but the graphics and control are screwed up.
Ms Pacman starts but crashes after the game is setup and ready to start.
There is a variation to the .rom file format. Looks like Freeintv supports the intellicart .rom file but not the cc3 .rom variation. Not sure if .cfg files are supported or if it depends on a database of cartridge configurations. Cfg file support would make it easier to support new games.
Defaults to widescreen aspect ratio rather than 4:3.
I’d like to see Netplay support be a priority for Freeintv. The Intellivision has many good games that are for two players only.
