Im afraid it isnt possible to have vice city on the gp32,Due to lack of Controls and the hardware issues of the gp32.
The playstation has a cpu speed of 733 mhz (Correct me if im wrong).
Plus the general thumb for coding is 6 x the gp32 hardware specs compared to the system needing to be emulated. The gp32 runs at 180 mhz at max,Even that is no where close to the speed of the playstation.
The gp32 also lacks 3d hardware.Making it difficult to make it work. You may think doom is 3d but infact it is 2d,For example look at the sprites,They are allways facing you hence being 2d.
If the playstation was the same speed of the gp32 of 133mhz,We still wouldnt see it as the emulaotr has to emulate the sound,Grapics etc. Not just like its playing the game.
Also The games are on cds , CDs are at maximum 800mb, An SMC which s used for the gp32 (Black card with a shiny metal/Copper surface) Can hold at max 127.5mb.
However it would be possible to make a game similair but say GTA1/2 But it would be possible due to no source code provde,Maybe in 5 years we will see some but forr the time being it wont happen.
Conclusion:
We wont see any GTA series on th gp32 at the moment,Maybe with the next gp32 we will see a psx emu,But at this moment its most likely not to happen.
I hope this helps you.
