Historically, the most famous attempts to bring VCS to PC were "Total Conversion Mods." These were massive projects undertaken by teams of unpaid modders who attempted to import the entire map, storyline, and assets of Vice City Stories into the engine of GTA San Andreas .
GTA: Vice City Stories introduced mechanics that were revolutionary for the time but are now standard:
A: The original PSP’s ad-hoc multiplayer does not work on emulation. However, the fan mod team had created a LAN multiplayer mode before the DMCA takedown.
The game was built specifically for the PSP’s hardware. The rendering engine, draw distances, and particle effects were optimized for a small screen. Porting that poorly optimized code to variable PC hardware would require a full remaster—something Rockstar hasn’t shown interest in since the GTA Trilogy fiasco.
