Charset ROM location changed on ZXPand?

[Sdw]

When I test-ran my demo Somwhat Less Limited Capabilities on my newly acquired ZXpand, I noticed that the scroller was completely garbled.
I read the data for the font from ROM location 0x1e00 and forwards, and it worked fine when I ran it before using a normal 16kb expansion.

Does the ZXpand ROM remap the location of the default charset somehow?

RTFM.
Yes. Zxpand disabled the character rom.
To be able to use it you can disable it after loading by adding a X to the load command.
I don't remember wether it is , or ;
So please read the manual. It does contain valuable information.
kind regards Paul

Oops! Well, in my defense the ZXpand was so easy to get started with that I didn't find any need to read the manual!

The character set has not moved, it's in the same place in the original ROM. But, what the Z80 CPU reads has changed. When the ZXpand is in use, a different ROM is mapped into the same address space as the original ROM. The area where the character set was is now more machine code. Hence when the CPU reads this area, it does not read the character set data.

Ran it again now with the ;X parameter added - worked like a charm.
Sorry again for missing that this was mentioned in the manual!
