Sega Game Gear PAR Hacking - Brief Info
Notes
24k of RAM (0000-1FFF)
Base Count Decimal (BCD): Hex values in the RAM are the same as they appear on screen. i.e. 20 is $20 in the RAM, not $14.
PAR Code Format: 00XX-XXYY - 8-Bit RAM Write (C000-DFFF). XXXX is the RAM address, YY is the value.
Hacking PAR Codes
The only emulator with built in code search I've seen is CHASMS, but it only has Known Value, and it will only show you the results when there's 1 left.
So how do you hack Game Gear PAR codes? Use the Sega Game Gear/SMS Super Search Tool to compare save states. It automaticly
converts from the address it finds in the save state to the PAR address. The actual save state specs are listed below.
| Name | RAM Location |
| CHASMS | $9E to $209D |
| Dega | $80 to $207F |
| eSMS | $18 to $2017 |
| Meka (Win) | $67 to $2066 |
| Past-O-Rama | $8030 to $A02F |
