Saves broken in C64 Ozmoo build

Hello,

I'd like to play the Ozmoo build to get the C64 REU features, but whenever I try to restore a game, the screen just gets messed up and eventually the game crashes :-/ (It draws text only on the first two lines of the screen and after trying to type some commands, all characters get messed up with random bitmaps and it crashes.)

Previously, it did work. At least the last two versions haven't worked for some reason… Would you happen to have any idea why?

Thanks

Are you saving on the game disk or on a separate disk? If you are saving on the game disk, that definitely can be the cause. The notes that come with the game explicitly say to use a separate disk instead.

PS: I have now re-read your post. And frankly speaking, I don’t understand. Have you rebuilt the game using the z5 file with the Ozmoo builder? So you made your own disk where REU is enabled? Could you be more precise so I can understand what you did? If this issue is related to Ozmoo, I need to involve Fredrik and Johan. But I need them to be able to reproduce the issue. 

Please also enclose if you’re playing this on real hardware with a real REU cartridge or what the environment is that you play the C64 version in. 

One more thing to mention: if you rebuilt the disk using the Z5 file e.g with the Ozmoo Online builder, we are not talking about an issue of the game and your post here is at the wrong place. The disks I distribute here have REU disabled but work just fine. In such a case the way would be filing a bug report with the Ozmoo team. I forwarded Fredrik this thread, so he might give advice on that!

Yes, I did build it myself with the Ozmoo web page from the z-file.

I am running on a real C64 with a 1541 Ultimate II+. I have the 1541U’s REU emulation enabled and I'm loading from disk images.

For the save disk I created a separate disk image which I mount when required.

A previous build used to work with this same exact setup. Not sure when exactly it was broken, but I have a vague recollection that Ozmoo was updated sometime last year perhaps? If this is down to Ozmoo (which makes sense now that you say it), then that would match with when it last worked for me.

I would like to help the Ozmoo guys in testing this, but I'm not sure how to contact them without sharing my email in the open… If they happen to use Mastodon, they can DM me: https://mastodon.gamedev.place/@harri

If they don't, they can get my email by placing my first name on the left side of the @, and my verified website URL on the right side :-)

Thanks for the reply! It's an awesome game, so I'd like to keep playing it, even though I actually have to start from the beginning now :-) After the REU experience, it's just hard to go back to stock C64…
