Yeah, that's probably it. You need 540672 bytes of archive to hold that app. Thanks for trying the beta!

I got it working!  Very Impressive, I think I'm gonna buy an adapter so I can get some sound out of this thing   I guess I didn't really know what to expect, but it works quite well.  I was surprised that the calculator could do grayscale like it can.  One question I do have, is flicker unavoidable?  It seems to be extremely bad at 75% and 100% I guess that the calculator has to make do with emulation on a smaller screen.  I just wanted to make sure it wasn't an OS, software, hardware issue or maybe if there is some way of reducing it to a less than distracting level?  I'm totally fine with a medium high contrast setting at 50% screen size(best for flicker), but only when I'm not dreading having to zoom in and around to read text.  It really is fascinating that you were able to make something like this, and it's even more spectactular watching it work!

Now that there's a mode with interrupts, is perfect grayscale asking too much.

I'd say perfect grayscale is a little out of reach. As it is, TI-Boy struggles on quite a few games just to attain a somewhat playable speed. Adding in a feature that would consume at least half of all CPU time would slow down emulation even further. It also wouldn't be compatible with sound, as that uses all the crystal timers.

I guess for the few games that use very little processing power, if the user has sound disabled, perfect grayscale might be possible while attaining decent emulation speed. Granted I haven't tested many games, every game I've tested so far would not fall into this category.

You'll have to test it. You can test games in wabbitemu before you put them on a real calc. 83+SE/84+SE can handle up to 1mb roms, 84+ can handle up to 256k. Games that contain 32k extra ram will no run on calcs with the missing ram pages. The incompatibilities can be caused by alot of things. Its a gameboy emulator on a z80 calculator, it's not going to perfectly emulate all the gameboy hardware.

do roms patched by a .ips file work with ti-boy?

If they work in a normal emulator, they have a fair chance of working in TI-Boy.

I have a question calc84maniac, have you managed to fix the timer issue with beta 1.07?  I have a friend that is a console collector, and he was amazed how a TI Calculator can run a gameboy game with sound.  I was going to help him program his (lucky him he has hardware revision d).  I tried the Mario Land on my own calculator and the sound for the world music was all wacky.  I was just curious if you have fixed the timer issue, that way the game sounds good.   

You can look forward to that fix in the next version of TI-Boy

I must certainly will!  I'm not sure, but it seems when I run beta 1.07, WabbitEmu crashes on Kirby's Dreamland and Kwirk. (the calc screen freezes)  Mario Land runs fine. (never tested either of the two on my real calc)

fred30w, it looks like the reason Kirby's Dream Land was crashing for me was a glitch I accidentally introduced in the development version. Beta 0.1.07 seems to run the game fine. Are you using the latest version of wabbitemu from http://wabbit.codeplex.com/?
