Download Doom (GBA) - PC Doom Total Conversion ROM Hack

This patch completely converts the game from using the dated stripped down Jaguar Doom engine and instead switches it to a new homebrew port based on doomhack's PrBoom port to the GBA.
Meaning, higher quality sounds, full non-simplified PC Doom maps, better framerate (yes!), graphics and music (far better music, they play in the correct level now!)

The HUD has been changed to match the one from the GBA Doom II PC Conversion pack.
Unfortunately this homebrew port doesn't contain multiplayer.

Patch the original retail GBA Doom rom with Lunar IPS and this GBADoom-PC.ips
