Is Anyone Working on a GB/GBC emulator for the PRIZM?
« on: February 26, 2012, 05:50:16 pm »
Is anyone working on a gameboy/gameboy color emulator for the PRIZM? How about GBA? I'm just wondering because it is a cool idea for someone to try.

Sadly not at the moment, but it would be very possible, since it was done on both the TI-84 Plus and the TI-Nspire. GBA would be impossible, though, since the much more powerful TI-Nspire could barely handle GBA emulation. It would most likely be GB and GBC.

Although finding the ROMS that work is not very fun :( and sometimes illegal depending on the game. I'm more into simple porting the games directly

yes, technically, one of the things I'm looking into while disassembling the OS is the ability to have a GBA emulator.

Yeah usually we can't ourselves provide links for legal reasons, and figuring out which game is legal to share is hard. Usually Google nowadays does a pretty good job, though, compared to a few years ago, else there's file sharing sites.

But yeah for GBA I'm curious if it would even be possible at all, because the Nspire Clickpad ran at 150 MHz max and could barely handle GBA emulation (only one mapper at once was supported, IIRC), so now imagine on a 116 MHz processor.

More like only one mapper was supported because I only implemented one of them :P

I don't even remember that. Was it just a tech demo? Did you ever even post it in a topic? O_o

I think that a Gameboy Color emulator on the Prizm would work.

Game Boy Classic:
CPU: 4 mHz, 8-bit CPU, a 160 x 144 dot matrix monochrome LCD display
;kind of sounds like a Ti-84 :P

Gameboy Color
CPU:Sharp Corporation LR35902 running at 4.19 MHz.

The Gameboy advance
CPU: 16.8 MHz 32-bit ARM7TDMI with embedded memory.

Gameboy and gameboy color are definitely feasible. GBA... probably not.

Well remember we don't just take the RAM and CPU into account though, but the graphic card or video capabilities as well, which, I think, calculator lacks (on top of that the PRIZM display is capped at 20 FPS or something)

Also, if we can support GBA on Prizm, doesn't it also mean that we can make sound come out of the calculator without any earphones?
So, my guess is, probably not :P

I think a gameboy emulator would already be a massively outstanding achievement, let alone GBA.

Well since GBC emulator is possible on the Nspire, shouldn't it be not very hard to do on a Prizm?
Or is it a whole different level?
