I'm making a game like Subway Surfers for the PSP (PlayStation Portable). The game is written purely in C and MIPS32 Assembly and runs directly on the PSP.
This is a very ambitious project as the PSP was released in 2004 and has very limiting and constraining hardware: a single-core CPU, a fixed-function non-programmable GPU, a clock speed of 222-333MHz, 32-64MB of RAM, and 2-4MB of VRAM.
The game is written completely from scratch using a custom game engine built specifically for the PSP.
