Emulator file stores compatibility settings for 898 Title IDs (as of 3.65 firmware). Additionally, settings can be supplied by title_specific.bin files. Title IDs are hidden under simple hash, which Sony borrowed from PSP POPS. That's not only similarity between two compatibility systems. Same like on POPS single config entry have 4 bytes ID and 4 bytes value, also here Sony decided to start count from -1, so config ID are in range of -1 - 0x1F. Which gives 33 possible settings per game.<br><br> | Emulator file stores compatibility settings for 898 Title IDs (as of 3.65 firmware).

Current version of Vita Adrenaline seems to break internal table settings and use own values in ScePspemuInitTitleSpecificInfoPatched. This is probably reasoning why some games run better outside of Adrenaline (in ARK for example). This is because adrenaline hook's function responsible for reading config table and use own code that totally skips internal table. This can be easily fixed, just remove ScePspemuInitTitleSpecificInfoRef hooks. | ||
