Re: Preserving Arcade Core High Scores

Yep, the option has been broken for ages! I never noticed because mine had autosave turned on at some point before the option disappeared when I tried to hide the option for the one game on that core that doesn't have NVRAM and messing it up somehow :D I've raised a PR with a fixed version and quick framework update, just got to wait for that to be...

Re: Preserving Arcade Core High Scores

It's supposed to have auto-save - it's in the code at least.. It's been 3 years since I did it so the memory is fuzzy though :D

I will give it a try when I'm back home and see if it's something silly. you'd think someone would have noticed in the last 3 years!

Re: Centipede Speed Up request

I don't think I built the 800% version, I think it was funkycochise? I don't have the source for it exactly... I was trying to get 800% and 1600% options in there but the core is a bit unstable and wouldn't build repeatably after the change - and then I got busy and somewhat forgot about it :| I may have time to look at this over the holidays, have...

Re: How Difficult Is It to Add Vertical Flip to a Core?

I concur with bazza, nothing to lose by giving it a try. However... It's certainly not the simplest way into learning core development! The level of difficulty in implementing vertical flip will vary hugely depending on the way the original hardware draws to the screen. If you are lucky and the system uses a frame buffer (like Juno First which I'm ...

Re: Preserving Arcade Core High Scores

The core author @enceladus does mention it's on his todo list in the readme, so no harm pinging him a DM to let him know there are people who'd like to see the feature :)

I could give it a crack at some point if not, but my limited spare time at the moment is all being consumed by my new core project!

Re: Preserving Arcade Core High Scores

I noticed today that my Pac-man highscore was blank. I tried playing a game and the blank high score was filled but not saved. I noticed the core menu doesn't have an Autosave Highscores option. I tried deleting the nvram for Pac-man but it didn't make any difference. Any idea what I'm missing? If the Autosave option isn't there it sounds like you...

Re: Centipede Speed Up request

Assuming you mean fast polling, then no I don't think that changes the frequency at which the MiSTer framework sends mouse updates to the core, it just increases the frequency with which the number that the framework sends is updated. So it shouldn't affect the actual speed, just more accurately reflect changes in speed. I think.... I hope that mak...

Re: Centipede Speed Up request

So based on my understanding of the way the original hardware works, it definitely is trying to be linear - but the game only reads the encoder values so many times a second, and that read is in no way synchronised with the rotation, so the results can be a bit weird on occasion. There is definitely a maximum theoretical speed you can move, as the ...

Re: Centipede Speed Up request

I've just pushed a new version with a 400% speed option, should be available for update within an hour or so...

(the reason it's 400% is mainly because x2 or /2 is much easier for the FPGA and causes less stress on the core!)

Re: GRS Trackball

It's crazy how wide the range of sensitivity on these devices is! I thought 25%-200% was going to be enough :)

I've sent @zeosstud a test version with 400%, if it works ok I can roll the same change back into MC no worries.

Hello,
Anyone interested in trying to update Centipede so the trackball sensitivity could be higher, it goes to 200% currently but several of use seem to agree even more would be helpful..

Thoughts?

Zeosstud

The core is getting a bit flaky and might not enjoy adding another option to the mix, but I'll give it go!

Re: Lady Bug Vertical Flip

I enabled vertical flip over HDMI in the latest update because that is a MiSTer framework feature now and so was just a couple of lines of code and a re-compile. Unfortunately vertical flip over VGA is a much harder piece of work as it needs to be worked into the core video circuits, no shortcuts available! I gave it a try a while back and did not ...

I don't think we have a good list of missing computer cores yet, but moondandy has been compiling a good list of missing console cores here:

Consoles can be simpler than computers anyway, as you don't have to deal with tape loading and othe peripheral nonsense, so might be an easier starting point :D

Pengo set 1 has just been updated with a fix - please give it a go and if all is well I push it over to the alternatives.

Re: Preserving Arcade Core High Scores

My saved scores still had my name in multiple times, but when I loaded Pengo set 1 and then opened the OSD it saved over scores 2 to 5 like you say :( It must have worked before, or my save wouldn't have had those initials still in.. I will investigate further (aandd probably add the autosave capabilty to the alts, which I must have missed before).
