Well, Joey has updated the Phoenix emulator has been updated again, and this time, no graphics bugs!

Hello again everyone, there is good news today, i have fixed the graphics bugs in my phoenix emu. Everything is working really well now and it is either running at the full 60fps or very close to it. To fix it i just needed to change the size of my bitmap to 256×256 so each store queue transfer was 256byte aligned, i was just aligning the first one (thanks to Regex for the info). So now that that is sorted out i can work on adding support for pulling the palette from the roms instead of using the premade one because the colors arent right. Also i will probably be starting to use the TA soon so i can move the game to the center of the screen. Well, have fun with this new release!
