/**************************************************************************
*
* 39in1.c - bootleg MAME-based "39-in-1" arcade PCB
* Skeleton by R. Belmont, thanks to the Guru
*
* The program ROM appears to be encrypted, please help if you can!
*
* CPU: Intel Xscale PXA255 series @ 200 MHz, configured little-endian
* Xscale PXA consists of:
* ARMv5 instruction set without the FPU
* ARM DSP extensions
* VGA-ish frame buffer with some 2D acceleration features
* AC97 stereo audio CODEC
*
* PCB also contains a custom ASIC, probably used for the decryption
*
