I also found another issue I'd like to mention:
King 2.50(R30 version) is protected against RAM upgrades. If you install more than 512KB RAM, it will still detect the RAM expansion. But it limits RAM usage to only 128KB. So, if a person wanted to make their R30 stronger by installing more RAM, King 2.50 will actually become weaker.
That's interesting (and sound a bit strange).
How did you find this? By disassembling the code (using the debugger) or by looking at the RAM usage?
Could this problem be solved by patching the 2.50 ROM, so that it uses at least the usual 512kB when installing more RAM?
