==Compatibility Settings==
Emulator file stores compatibility settings for 898 Title IDs (as of 3.65 firmware). Additionally, settings can be supplied by __sce_menuinfo or 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>
'''Warning!''' 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).
===Title ID Hash generator===
def checksum(string):
x = string[0:4].encode('ascii').hex()
x = int(x, 16)
#print(hex(x))
y = string[4:]
y = int(y, 16)
y = y + (y << 12)
#print(hex(y))
suma = x ^ y
print(hex(suma))
checksum("ULUS01986")

Compatibility Settings

Emulator file stores compatibility settings for 898 Title IDs (as of 3.65 firmware). Additionally, settings can be supplied by __sce_menuinfo or 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.
Warning! 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).

Title ID Hash generator

def checksum(string):
	x = string[0:4].encode('ascii').hex()
	x = int(x, 16)
	#print(hex(x))
	
	y = string[4:]
	y = int(y, 16)
	y = y + (y << 12)
	#print(hex(y))
	
	suma = x ^ y
	print(hex(suma))
