The SWRAM version uses the 2.5KB at the end of the 16KB Sideways RAM slot as filesystem workspace. You can verify this is the case, if PRINT ~PAGE returns E00 rather than 1900.
Yes, it is &E00. I thought that was odd as my original BBC Model B by default had PAGE set to &1900. That explains why it's &E00.
What version of MMFS is being used? *HELP should tell you this. I suspect it wll be rather old (1.39? which is 6 years old now).
1.50
The other possible issue here is because MMFS is in SWRAM, it's more prone to getting corrupted if the application mis-behaves and randomly writes to memory.
Well I have DIMmed all the chunks of memory I use, and other than page zero user mem (&70-&8F) I don't deliberately write anything anywhere else, but then I have seen some odd random behaviour recently when I try and blow up an alien, so there's definitely something amiss. I did find a bug where I'd messed up my position in the stack which solved a big issue so I thought at first that might have been the problem, but it doesn't seem so.
