Copy and change GbaWadUtil

add to WAD HELP2.LMP, STBAR.LMP, TITLEPIC.LMP, WIMAP0.LMP
lower details of pictures by only using even columns and letting odd columns point to the previous column. See WADptr
shave of some unused bytes in posts, map textures and map patches
replace texture names by numbers in sidedefs and sectors
change the palette values in the WAD so it's not necessary to do (*palette++) >> 2 in i_system.c

What would be the lowest storage requirement if e.g. the WAD only contaned E1M1? Just got a neat industrial device using a 386-based microcontroller that runs everything off (currently) 1M of flash EEPROM... would be fun to at least get something going :D I've ordered chips to hopefully double that but not sure it'll work...

Around 226 kB.

Woo this might work, "just" need to wrangle my way into transferring data onto it...

Note to self: See RP2040 Doom for more compression tips.

Hi! You might also want to try Squashware Doom which I put together earlier this year:
