Playing with commit 916020e. Very good job so far, keep up the good work! Pokemon Fire Red no longer lags before wild pokemon battles, but theres just one transition for trainer battles that is laggy. Also, before this update, looking at your trainer card in fire red would freeze the game, but now there's just a little lag. No problems with Pokemon Ruby. even the dark cave effect works now, I recall that not working in previous versions. Super Mario Advance 2 works fine but the borders of the text boxes flicker. Also, I was testing that one gba flappy bird homebrew, and it also works great, but the background doesn't scroll like it should. Anyway, thank you so much for creating this, and I hope it will gain more support!
edit: the pokemon games i tested, i sram patched beforehand. Same for SMA2. Also, Mario Kart Super Circuit and SMA4 work flawlessly
