one of the performance things done in this code is that the blit function is fully inlined everywhere. given assembly, that probably means it's a macro
Foone🏳️⚧️oh god.
the compression has two varieties. There's no header to determine which one is used. The difference? if the RLE runs are length-1 or just length.
Foone🏳️⚧️oh hey this is interesting: See this palette-cycling-ass effect?
The palette never changes. This game must be doing that /in software/
Foone🏳️⚧️okay, so this fire effect is being run dynamically: it's iterating over part of the screen buffer, and lowering/raising all non-zero pixels, and when those pixels hit values 90 or 111, the increasing/decreasing reverses.
