// ISG 'Selection Master' Type 2006 hardware
/*
This is a 'multi-game' cart system (only the operator can select the game, via a dipswitch exposed from the cartridge)
The system is designed to look like a PGM system (the ISG logo and fonts are ripped straight from original IGS material,
and the external casing of the unit is near identical) The system does NOT however run PGM games, the cartridges won't
fit, and the hardware is basically a bootleg of Sega System 16 instead of PGM! So far only one cartridge has been seen.
There are various levels of 'protection' on the system
- Address XOR + 16-bit bitswap on the BIOS ROM and Cartridge ROMs
- A device which performs a 32-bit bitswap, used to produce decryption keys for the data compressed on the cartridges
- An alternate way of reading the cartridge data through a port, which causes an additional 8-bit data xor to be applied
- A simple hardware RLE decompression device used to decrypt data for the BIOS (the games use a stronger software
implementation instead)
The PCB is entirely custom SMT components, as you'd expect from a modern bootleg, all chips have had their surface details
removed.

/*
ISG 'Selection Master' Type 2006 hardware
This is a 'multi-game' cart system (only the operator can select the game, via a dipswitch exposed from the cartridge)
The system is designed to look like a PGM system (the ISG logo and fonts are ripped straight from original IGS material,
and the external casing of the unit is near identical) The system does NOT however run PGM games, the cartridges won't
fit, and the hardware is basically a bootleg of Sega System 16 instead of PGM! So far only one cartridge has been seen.
There are various levels of 'protection' on the system
- Address XOR + 16-bit bitswap on the BIOS ROM and Cartridge ROMs
- A device which performs a 32-bit bitswap, used to produce decryption keys for the data compressed on the cartridges
- An alternate way of reading the cartridge data through a port, which causes an additional 8-bit data xor to be applied
- A simple hardware RLE decompression device used to decrypt data for the BIOS (the games use a stronger software
implementation instead)
The PCB is entirely custom SMT components, as you'd expect from a modern bootleg, all chips have had their surface details
removed.
