NOTE: I recommend playing Doom 32x: Delta by @Roebloz to get a bit of background on this.   The original GBA port of Doom used the simplified maps found in the Jaguar port as well as the 32x port. However, the ROM hacks Doom 32x: Delta and its friendly cousin Doom GBA: Delta fixes this by adding the original PC maps back into both ports. This hack uses the optimised Doom 32x: Delta map-set, meaning all maps run and play good.   SIGIL RELEASE POST     SCREENSHO
