Known Bugs

• The game may crash at times when used in certain emulators, which are known to not be 100% accurate with emulation. These emulators are No$GBA, VBA, MyBoy, JohnGBA, GPemu, Eclip´se, and sadly the virtual console of Nintendo 3DS. It is uncertain if I will ever be able to fix that. Recommended emulators are mGBA, VBA-M, RetroArch, Delta emulator, PizzaBoy GBA and GPSP.
• Fast forward speed is kinda laggy because of the High quality music mixer using plenty of memory to run. (But we got high quality music, yay!).
• When using a Poké Ride, the picture of the Pokémon and the cry will be empty/question mark. This is due to it’s pending to find a fix for an issue caused by overwritting a Pokémon of your party to show a different Pokemon’s picture. Visual bug and will not affect any Pokémon from your party.
• Some overworld tiles and blocks may not be correct. Minor issues to be resolved.
