HUGE Credit to Executec, and ESPECIALLY huge credit Geotale/EmulatorsOnScratch, their work on Wave and other emulators is amazing and you should check them all out. The changelog is below. WARNING: Emulators have not been thoroughly tested and may not work right, if at all.
Next oxiti8 Dual-Emu build: https://scratch.mit.edu/projects/445482302/ I added Geotale's Chip-8(Fixed! Now with sound and other changes), NDS(Removed due to size issues), and GBA (V0.0.5) emulators, making this a more viable emulation solution. I made the "Import ROM" button its own tile, and changed the background to one more resembling EmulatorsOnScratch's Wave menu. The main menu now loops around when you scroll to an area with no icon. WASD support for the main menu is now included. I added "Ultimate "Hello,World" Esolang Interpreter" as a bonus feature. Commands specific to UHWEI Wave: "clear": clears the console.
