AS:
Current ROM code barely contains some valid SH-2 opcodes but not enough for a HD64F7045F28. i.e. It doesn't contain VBR set-up, valid irq routines,
a valid irq table and no internal SH-2 i/o set-up. sub-routine at 0xe0 also points to 0x4b0, which is full of illegal opcodes with current ROM.
Two possible reasons about this:
* U11 isn't really empty or ...
* There's an internal ROM (pages 43 and 78 of the HD64F7045F28 manual hints that). And really, good luck into finding a way for trojanning that
(exotic usage of the SCIF seems the only possible route)
The HD64F7045F28 manual says that there's an on-chip ROM at 0-0x3ffff (page 168), meaning that this one definitely needs a trojan/decap (and also an SH-2 core
that supports the very different i/o map ;-)
Guru:
It's called Hide and Seek. I don't know the manufacturer.
