hey guys^^ @ade, cool emulator gui ;D you could implement last-state function. here is the method i'm thinking of, the gui could handle (mario is an examplename): if the emulator exits, the gui renames the savesstate of the loaded game to sth like "ssmario.ss0" (or whatever) and it saves the laststate as "mario.ss0". When the game is reload, optionally you get asked if you want to load laststate. If yes, it loads "mario.ss0", deletes it and renames "ssmario.ss0" to "mario.ss0" (so the normal savestate can be loaded). If no, it deletes the laststate and just renames "ssmario.ss0" to "mario.ss0". That should be a method, which should be 100% operatable off the gui (but i'm not a developer, so i am not that sure). This renaming method could also solve the "there is only one savesslot" problem I hope my thoughts will help you with developement of a new feature best regards, danzo^^
