changed IREM cpu decryption to be 'real-time' (it's a feature of the CPU)
moved decryption table setup to 'config' struct for the CPU. added latest tables from robiza, making Risky Challenge playable, promoted it to working told CPU core to not decrypt code after brkn instruction, enabling it again on iret, allowing me to remove several 'don't decrypt range' hacks in robiza's code. updated all drivers accordingly. currently the disassembly is a bit weird now, this will need looking at.

8 MHz, but at least it's usable.

- Probably all games use a nec V35+ cpu: for gussun and risky challenge

we need a proper V35+ core for the use of the 0x63 instruction (brkn, to call a unencrypted
