It seems to remove some subtle visual glitches in Metal Slug 2. Not sure if this affects the performance negatively compared to the previous patch (which overclocks more components).

I've been running emulators since 20 years and just a short while ago I moved to FPGA only because I've been surrounded by people in my community that moved beyond emulation and started using FPGA and convincing me of its pure way of playing the good old games. Not because it is easy but because the hard work setting it up leads to the 1:1 experience I once had.
I played Metal Slug when it came out on the Neo Geo back in the day and it had slowdowns...

Now 24 years later we moved passed emulation and we're on a forum because we want the 1:1 experience and there is talk about how shitty the slowdown in Metal Slug is? Didn't you play the game back in the day? If yes, and you still want to "turbo boost" so that you're not bothered with the 1:1 expierence, please buy an 5K pc with a 3090 and an 8K monitor and run an emulator.

My 2 cents

Which one do you prefer for Metal Slug 2 for example ? 18Mhz or 24Mhz ?

Just saw this, I'm also curious if this option will be added officially!

(posting for visibility)

i would love to see this in the main distro

I would not want to see it. the game is behaving correctly now. Its the same as real HW

It would be a toggle though, not on by default, so users could choose

You don't see the debate in on another thread. For an unknown reason there is some purist that don't want it. Even telling them this is an option that can be disable is too much for them apparently.

The neo geo core really need some qol options, like overclocking or a pause button (or assign the "freeze" dip switch to a button ?). And i think the only way to have it is to give something to a core dev that will do it. A little in the model of the bounty at retroarch.

Yeah, I agree. I remember when I brought up that the buttons were "wrong" in relation to the original Neo CD controller and it sparked a huge debate. Eventually the right person was able to add it lol

it's worse than that

it would be an OPTION .... that you CAN ... optionally ... ENABLE...when you want it

i dunno, if someone has an actual argument then we can discuss and counter-argue, but it seems to be only "ehm, no thanks" so.. it's moot. let's just merge the OC into the core already.

I've spoken with several people, who refuse to play Metal Slug 2 Turbo or overclock their MVS boards, because "it's not the original experience". But the same people also never play MS2, because without any slowdown removal it's a shit experience.

And now we're supposed to respect their opinion that removing slowdown should be forbidden from others, too?

Feels like I'm taking them crazy pills...

Has anybody attempted to modify the core to allow for multiple clock options and make it changeable on the fly via the OSD menu?
I'm not talking about having separate cores for each desired clock, but one core, multiple clocks?
And make the system (including the new CD features) completely usable on all clocks?
If they have, then they should try doing a pull request and see Sorgelig will accept it.
Adding clock lines to HDL that can change on the fly can be tricky and sometimes it may not even synthesize properly, if at all, and introduce unintended timing errors in other parts of the core.
Not saying it's impossible, but can be difficult to implement and maintain when attempting to add new features (such as when adding CD support).

See https://github.com/MiSTer-devel/NeoGeo_MiSTer/pull/179

Changing the CPU clock as an option isn't very complicated, it's probably just that core devs rarely care much about features that didn't exist in original hardware.
