A word of advice: try to keep minimal load configuration to prevent hiccups while executing the PSP Homebrew Doom Legacy. The other slots are used for custom-created WAD files. Do note that the PC-PSP port has been designed to accommodate a total of 5 separate WAD files with one slot being reserved for the primary WAD file. The PSP homebrew version doesn’t include in-game music although it supports the multiplayer option. But that said, you also need to understand that the users will be able to witness only the NEW VISUAL LIGHT on the software rendering mode. The homebrew PSP Doom legacy promises the best version of old Doom games along with the latest options. The best part is that the ported version comes with a multiplayer capability option. Doom Legacy has been ported for the PSP Portable.
