As ever, as soon as you upload a new release, you find a few more things.

No gameplay issues - just visual issues on the final boss stage and the level 2 - bonus stage.

Gameboy, Gameboy Color, Analogue Pocket & Web v0.99a are up for now - others will follow soon.

As part of another experiment.  I noticed compiling for the Gameboy Advance with the Goomba emulator had terrible performance.  So with this release I am trying a new method using GBSenpai to recompile the source to work with the Gameboy Advance natively.

Good news... it compiles it to work with widescreen and the performance is great.

Bad news... music on levels 2 & 3 seem to mess up on initial testing.

I may create a version with music that works better and this will become what I release for GBA and potentially 2DS / 3DS too.

Update:  I have uploaded a 2DS / 3DS virtual console version for both the Gameboy and Gameboy Advance versions.  You can install via the FBA app

Update: Dreamcast, N64, Windows, OSX, Linux, Wii U, Chrome / Edge Extension versions added - only Dreamcast, OSX & Windows has been quickly tested so far.
