Reip's MAME Wip

[Diso]

Reip has recently updated his MAME log.

 

Working hard on Eolith games. This time I could make Hidden Catch  - ©1998 Eolith to work.

It suffered from a nasty bug in the Hyperstone cpu core, because it used a memory instruction which

reads data from the memory address stored in the source register, writes the data read in the

destination register and then increments the source register by 4, but... if source and destination registers

are the same? Well, it only incremented the register instead of reading the data from memory

without incrementing it. This is strange because they could have used a normal

instruction which does the same but doesn't increment the source register, but anyway....

probably the compiler was a bit crap
