little bit of help needed with this half life dreamcast build

[mizaska]

hello, so ive been exploring this undocumented prototype (the april 20 2001 build) for sometime, found some textures and other interesting things here and there (which im documenting soon), i still need to play trough the maps which is a bit hard since the emulator im using is buggy, thing is goldsrc for the pc does not like pvr files, when viewing the models in a model viewer the textures appear corrupt and broken, i figured that since model textures are in pvr instead of bmp it kinda messes up, i tried extracting the textures from the mdl but it still appeared corrupt, the textures show up fine ingame however
another texture issue is when opening the maps in worldcraft and selecting the right wad the textures still dont show up despite the map textures being in bmp, several objects and props dont load correctly too, this might be a general porting issue but still
help is greatly appreciated, i apologize if my techniques are stupid since im not a professional yet at exploring game files
