/*
Note about current c-chip eprom dump
the current dump is bad because data with address bit 0x200 set is missing (always read out as 0xff)
you can however locate some of the tables used by the current simulation code in the rom
for example
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B
00001128 07 80 02 09 03 00 4C
00001134 01 00 04 00 10 07 80 02 09 03 00 4C
00001140 01 40 04 00 20
is the following data from machine/opwolf.cpp
static const uint16_t level_data_04[] = {
0x0780, 0x0209, 0x0300, 0x4c01, 0x0004, 0x0010,
0x0780, 0x0209, 0x0300, 0x4c01, 0x4004, 0x0020,
however without the correct dump of the cchip eprom we can't run the actual cchip code
