PSPColem is a ColecoVision Emulator for PSP.

Changes:

– Save state files are now saved using gzip compression (with STZ as file extention). It’s much faster to save or load states now. You can use gzip or 7-zip to convert old STA to STZ. STA file format is still supported for loading, so you convert your previous saved files inside the emulator.
– Save state dates are displayed in the emulator window (it’s now easier to identify and to load the right save state slot)
– New graphical functions with new smoother render modes. It uses the PSP GPU for rendering, it does not run faster, but it’s a lot smoother.
– Add a new fullscreen option (render mode max)
– Bug fix in Rom file requester
– Multiple keyboard mapping feature (Thanks to Pou-chan) : You can now toggle between three differents keyboard mapping using L/R Trigger keys
