Er... Why is it written on the first page of this topic that the version 0.1.00 brings the compatibility with newer hardware revision ?

Because the Alpha version released in 2009 didn't support the newer hardware revision at all. Now it is supported for all games with 8KB or less of cartridge RAM (which is most games, but unfortunately excluding the popular Pokemon)

The problem was already the unsufficient RAM ?

Indeed. When I first made the Alpha version, nobody knew that TI had decreased the total RAM in the calculators from 128KB to 48KB. (All the TI-84+SE calcs I own are before that revision.) So, I wrote the whole thing without being aware of this problem. Now that I know, I'm able to make the Beta version to use only 48KB of RAM for most games. Unfortunately, with Pokemon I don't even have as much RAM as the GameBoy itself had access to, much less have any extra RAM with which to emulate it.

Yeah, so the problem is quite unsolvable. How much RAM does the GameBoy have access to (and needed to run Pokemon) ?

Well, inside the Game Boy itself there's
8KB Work RAM
8KB Video RAM
128 bytes of quick-access RAM
160 bytes of OAM (sprite) RAM
And then for Pokemon, there's 32KB of Cartridge RAM (which is the major problem, bumping the emulator requirements way over 48KB)

How many other games have Cartridge RAM, and how much do they have?

Any game that allows you to save has cartridge RAM, if I recall correctly. Most ones only use 8 KB or less, and games that need to store a lot of data (for example, all of your Pokémon that you have stored in boxes) use 32 KB.

can you make one where it does not get a save file on never calcs?

Right, for all purposes it is treated like any other RAM, except that it retains its contents when the gameboy is off (due to the battery in the cartridge)

Hmm... Could you include a selectable option that would allow you to utilize the extra ram pages for those calculators that do have them? (IE it would use the additional pages that are inaccessible on the calculators with 48KB RAM) Or would that be to cumbersome to code?

This is already implemented, yes.

What ? You said that you have several TI84+SE calc84maniac ?
Please don't answer, I'll be jealous. Add to this that they can run Pokemon.

Hmm, this thread seems kind of f-zero/project m-esque...someone bumps it and it looks like there's an update
