@arelav @Manic-Miner-123 I spoke with the author of some specific games a while ago. (RIP John Wilson, the Rochdale Balrog).

He found some sort of bug in Fuse. It appears the fault is in the loader when line 13 calls the 'randomize usr 65020' routine ... Fuse fails for some reason.

He actually rewrote the loaders for Balrog and the Cat, Behind Closed Doors II and One of Our Wombats is Missing so the games will load. I don't know if there are any other developers' games which are affected by the oversight.

Where the game is keyboard dependent, like text adventures, I use Fuse, not libretto Fuse (lr-fuse.

Most .tzx games should work though - where they don't it's usually the case that you need to select 128K machine or Spectrum +3.

In rare cases, but especially Russian games, you need to select a machine like the Pentagon and specific instructions, such as for TR-DOS.

@tuki_cat said in lr-fuse and saving configurations for each rom:

rk but have had no success - how do you save configs per rom in lr-fuse? I essentially want to save the configuration so that it uses the 48k spectrum for certain games and 128k for others.
I have seen this link, but this doesn't work for me - https://retropie.org.uk/forum/topic/5409/jetpac-on-zx-spectrum
I have tried running a rom and the tried selecting the "save game overrides" in the RGUI I get a meesage that tells the file has been saved, but the configuration does not work and I can'f find where it has saved the .cfg

Main Menu > Quick Menu > Options > [change keyboard controls there] > [click on the top "Game-options file.... [name of game]... Took me ages to work that out.

Thanks, I will do a bit more experimenting.

I have a Pi 3 model B, I will see if I can recreate the issues on that, if I can then they must be related to the image format

@rbaker

I don't see how he is breaking the rules here. He wasn't asking where to get roms. He wasn't posting roms. All he asked is if it's possible alternate roms might work in his case when the one he has isn't playing. That's a reasonable question any newbie would ask and it isn't breaking any rules.
