ROM Speed and Map Mode (FFD5h)
Bit7-6 Always 0
Bit5 Always 1 (maybe meant to be MSB of bit4, for "2" and "3" MHz)
Bit4 Speed (0=Slow, 1=Fast) (Slow 200ns, Fast 120ns)
Bit3-0 Map Mode
Map Mode can be:
0=LoROM/32K Banks Mode 20 (LoROM)
1=HiROM/64K Banks Mode 21 (HiROM)
2=LoROM/32K Banks + S-DD1 Mode 22 (mappable) "Super MMC"
3=LoROM/32K Banks + SA-1 Mode 23 (mappable) "Emulates Super MMC"
5=HiROM/64K Banks Mode 25 (ExHiROM)
A=HiROM/64K Banks + SPC7110 Mode 25? (mappable)
Note: ExHiROM is used only by "Dai Kaiju Monogatari 2 (JP)" and "Tales of Phantasia (JP)".



Really i don't see what means "92" :|

GoodSNES marked the ROM you're asking about with the "bad" marker.
