Re: Neo Geo CPU Overclocking?
@Jimxz
I won't say that your statement is wrong because it is your point of view and I respect it, but I totally disagree with.
It is a chance that we have the Mister which allows us to run games or apps on machines which are not findable anymore or if they are, at a horrible price, it is a chance that we can play games from 70-80-90's for most of them on CRT or LCD, And it is a great chance that the devs have been working hard to enhanced the results either by proposing filters, different speeds, turbos etc. They are always options that you can activate or deactivate, see this like a bonus. If I do not like a TV series I do not watch it full stop. Same here if you do no want turbo mode, simply do not use it. But think that what is maybe useless for you is more that useful for others. I can tell you that since I'm dealing with the Mister, any new core, option, enhancement that I saw have all a big sense to be.

Re: Neo Geo CPU Overclocking?
I would love to have this implemented as a toggleable option for the official NEOGEO core.
As long as it's not enabled by default than it doesn't matter if it breaks compatibility/accuracy. This is the same as the sprite limit hack on other cores, cool option but I want it off by default.

Re: Neo Geo CPU Overclocking?
People would tinker with and overclock original systems too. Wanting to have the option on a FPGA system isn't that strange. I have played a lot of NeoGeo on a real MVS system. Usually the slowdown isn't bothersome but Metal Slug 2 is some top tier slowdown. Sure there is Metal Slug X which isn't as bad in that aspect but it would be nice if Metal Slug 2 didn't have to suffer so much when it's clearly possible to do something about it.Jinxz wrote: ↑Fri Jan 01, 2021 12:26 pm To be honest I am completely lost here... 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
Re: Neo Geo CPU Overclocking?
Input lag is the biggest problem with emulators 5K pc won't do anything to correct this unless the specific emulator supports frames in advance which is relatively new and not many emulators have itJinxz wrote: ↑Fri Jan 01, 2021 12:26 pm To be honest I am completely lost here...

Re: Neo Geo CPU Overclocking?
Maybe people don't like the changes made in Metal Slug X as opposed to 2 people pic particular versions say Mega drive version of Street Fighter 2 Hyper Fighting over the Arcade could be nostalgia?
Re: Neo Geo CPU Overclocking?
Just my 2 cents...
People play games on different platforms for many reasons.
The cpu turbo on the snes core makes playing super castlevania a lot more enjoyable. It's also how the game would have run if the devs were skilled enough at the time but it was a very early release.
The point is that these features are optional. Personally I'm curious to give this neo geo hack a go because metal slug 2 is particularly terrible when it comes to slowdown, and to play this with minimal input lag through mister would be a far better experience than with runahead or some other software emulation alternative. I spent years trying to get an enjoyable, low lag experience out of retroarch and I've given up. Some games I accept will never be emulated on mister and those I am happy to play on retroarch with gorgeous crt shaders and tweak lag settings, but overall I'm tired of tinkering, every single game needs to be individually configured for latency and I'm honestly just done with it...
And I have an r9 3900x and a gtx1080, so not a slouch of a pc yet still emulating causes me headaches, particularly with audio latency and input lag.

Re: Neo Geo CPU Overclocking?
I agree with this. The new Lynx core has a turbo option for only the CPU and GPU, the audio frequency and music tempo stay the same. A lot of Lynx games are a bit sluggish, the Lynx was supposed to be 50% faster, but that was lowered to save battery life. IIRC the Lynx development kit also had better performance than a real Lynx.
Re: Neo Geo CPU Overclocking?
Wow, this thing is amazing, thanks so much for this, this makes a massive difference in Metal Slug.
Question I have for you, what is the .patch file? Is it possible to patch the newest core version?
I also would love a turbo option in the official core.
Re: Neo Geo CPU Overclocking?
Slow down in Metal Slug or Shock Troopers is from a programing issue and not a problem with the hardware.
Some Neo Geo games have just poorly optimized code. The fact that there roms hacks that improve the speed of the games in question.

It is my great regret that we live in an age that is proud of machines that think and suspicious of people who try to.
Re: Neo Geo CPU Overclocking?
Hi man, your patch still works great but there were some major improvements since then on the neogeo core (especially on the audio side).
Could you please port it to the last version and on blackwine neogeo arcade core fork as well ?
It'd we very nice of you.
I've tried to modify source files following the directions you've put in your .patch zipfile but all I achieved was compile failure.
Thanks !
Re: Neo Geo CPU Overclocking?
An update would be greatly appreciate indeed. If you can update this version sometimes, for example every 6 month to catch up the latest version of the core, it would be great.
Thank you
Thank you
Re: Neo Geo CPU Overclocking?
I have modified my original Metal Slug 2 cart with a Turbo patched EEPROM and added an overclock switch to one of my NeoGeo boards for switching between 12MHz and 18MHz - just for this particular game. There is some slowdown in all Metal Slug games, but MS2 is the only one where it's far too obnoxious to enjoy the game. I use defaults with every other game.Jinxz wrote: ↑Fri Jan 01, 2021 12:26 pm To be honest I am completely lost here...

There are a lot of people who refuse to do this, because they see slowdown removal as a violation of something holy and just. The same people also never play Metal Slug 2, because it has too much slowdown to be fun.
I suppose being nostalgic for something being shit is a thing, too.
Re: Neo Geo CPU Overclocking?
The patched MS2 rom and this overclocked core has made it my favorite metal slug game. 100% accuracy is great, but there are definitely some quality of life improvements that are welcome. Especially when they are optional. Best of both worlds.
Re: Neo Geo CPU Overclocking?
I don't understand much why this option is not here, when it is in other core. I don't know if developers see this as an heresy or if they just don't care and don't want to spend time to implement the feature.
Maybe it would be a good idea for the interested to organize a small donation with patreon or alike. I am definitively willing to give a little something to have this option.

Re: Neo Geo CPU Overclocking?
Hi.
Here is the 24MHz patched neo-geo core up to date.

Re: Neo Geo CPU Overclocking?
Thanks a lot !
Which one do you prefer for Metal Slug 2 for example ? 18Mhz or 24Mhz ?

Re: Neo Geo CPU Overclocking?
As long as there are no adverse effects, it's personal preference. I stick with 18MHz, but only because it's the highest real NeoGeo hardware can do. Most speedrunners play on an emulator overclocked to 64MHz, which eliminates all slowdown completely.capitaineflam25 wrote: ↑Mon Nov 07, 2022 9:32 am Thanks a lot !

Re: Neo Geo CPU Overclocking?
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.
