Game Boy Emulator Games for TI-84+ (Non-Silver Edition)?
« on: January 05, 2016, 09:04:34 pm »
Help! I'm looking for any good TI Boy Games that will fit in a TI 84+, the version that was created last year. Do they exist, or is there some other way to increase my RAM so I can at least play Gemini or Robot Wars?

Unfortunately, many of the "best" Game Boy games (ex. Pokemon, Link's Awakening) are too large to fit on a TI-84+. You'd really just have to use trial and error, finding ROMs for games that interest you and checking that they're 256KB or smaller. Metroid II and Super Mario Land are possibilities.

As for freeing up RAM: archive all the things, and use a shell such as DoorsCS or zStart to run archived programs. If everything is archived and you don't have any random stuff hanging around in RAM (might want to RAM clear after archiving everything you want to save), you should have enough RAM for just about any game.

Well, I tried backing up my calc and using Doors CS to run Gemini, but I still got a memory error. All of my data had been cleared but these.

If you are very tight on ram you might have to delete some archived programs too, as they use up a few bytes of ram.

All of my data was completely deleted, ROM & RAM, except for DCS7 & Gemini.

Did you also do a ram reset?

You could try removing DCS and using Mirage instead.

or remove all the apps as the games themselves don't need a shell to launch iirc?

The problem he's having is that Gemini is ridiculously large. On a completely wiped calc, there's only a few hundred bytes of wiggle room of RAM. If you have just a few dozen archived variables, their VAT entries consume these few hundred bytes and you can no longer run Gemini. I remember that I had this problem too, back when I was in school. So, now that I know how, I decided to do something about it.

I dove into the source of Gemini and made a couple of optimizations. Namely, I reduced two trig tables from five quadrants each to just one quadrant each and wrote code to implement the mirroring. But this slowed the program down a bit, so I also took some time to optimize the speed of some core routines until it ran as fast as it used to.

Hopefully I didn't introduce any bugs. I barely tested it, so it's entirely possible. But since you're eager to play the game, you can test it for me! ;)

You should post that on ticalc.org - for those without SE calculators!

Haha, that's our Runer. :D I'd second posting it on ticalc, (after a bit of testing) licence permitting.
