Official shmupmame Super Turbo thread


I have to agree with James chen on your sig. There is something special with ST on a cab. Nostalgia factor.
I was drinking my ass off at NL just past friday with damdai and a handful of players. Fun times every friday.
I still need to master sanwas though.


Interesting GroovyMAME testing results!!:,133194.0.html

Scroll down to Calamity’s post towards the bottom.



Dude… I can’t thank you enough. I noticed I was having a weird time playing in Linux, and this link has confirmed why. Im also feeling some delay with ZSNES, which also uses SDL, IIRC. I’m currently playing Super Metroid a few times so as to learn the maps and eventually try some speed runs, but the commands are a bit strict*, Square gate screws my precision and there’s input latency on top of all that.

*wall jumps are very important in that game for speed, and if you ever reach down or up microswitches while doing them, spin jumps are disabled, wall jumps become impossible, and you fall all the way back to the bottom.

Edit: if that (currently) last post is right, I will also be able to increase the USB poll rate in Windows XP, which I thought was impossible without major trouble, i.e., learning win32 and doing it myself.


Absolutely! Calamity’s testing shows .65 frames of incremental lag over the cps2 hardware. That is pretty phenomenal! I’ve done the usb polling rate tweak and it seems to further help. At that point we are likely hovering RIGHT ON TOP of the hardware.



sorry i haven’t followed groovymame’s development.

so it has .65 frames at best? that’s not better than shmupmame is it?

i didn’t go into the details of how shmupmame reduce the input lag (as well as groovymame).
can groovy or shmup take advantage of each other’s trick and make it even better?


regarding input lag. will it be reduced if I use a non-USB keyboard?
Eg playing the game on laptop.


Since the original developer of shmupmame is not supporting/replying on his forum, I couldn’t make any contribution to make it easier for ST tournament/practice.

OTOH the groovymame dev did the opposite, I have now attached a modified version of groovymame that does

  1. fast buttom mapping for P1 / P2
  2. fast save/load state – no prompting for slot numbers and you can easily map the extra 2 buttons on your stick to do save/load. Just turn on cheat > training mode + infinite time.


FYI, piFBA was released for the Raspberry Pi. CPS2 now runs at 60FPS, but I am experiencing significant input delay. If any Linux gurus with a Pi want to download the src and mess around, please do so. I think this could be an excellent, portable, low cost alternative.


this has potential to be huge for 2d fighters because those raspberry pi things are only like 35 bucks a pop. Maybe rufus can take a look into this.


Mini ST as the future?


I think the biggest problem for ST has always been the lagless display, now that we have solved the custom input controller issue (ud-cps2).


They simply don’t make truly lagless displays for modern gaming. We either have to adapt and choose the least-laggy LCD which are commonly available, or count on a few guys to sling heavy CRTs everywhere.


is there any difference in lag if you disable the BGM and the backgrounds through cheats?

I played Vampire Savior and by doing this I think game felt a little more responsive


Are there any video setting (audio too) to do in addition the game speed to have the most closest arcade experience? I use the Shmupmame v4.2 Qt GUI + Command line (win 64-bit) and play 2X (97% game speed is already configured). There are some chance to run Shmupmame at Raspberry Pi and play 2X with many arcades(or pads) being exchanged like a offline tournament and works fine like a regular PC?


Jedpossum determined that disabling the related routines alters game speed. It looks like they are part of the cause of different speeds in different stages. Just disabling backgrounds in MAME, though, I don’t know.


I have read through the whole thread and I’m still a bit confused about the speed setting. When you all refer to “change speed to 97%” are you talking about the “main cpu overclock” setting or something else that I’m missing? I may be wrong due to the low quality of the videos I have watched (Gamespot Versus etcetc), but I think it seems a tad too fast in comparison.


Is the general consensus still that Shmupmame still provides the closest representation of the ST arcade experience? I read somewhere that the latest version of Mame was fairly accurate too having been tested at Evo. Just wondering as Shmupmame hasn’t been updated for a couple of years now.


Tested at Evo? Been to Evo the last few years specifically for ST, and at least on the floor space, we weren’t using MAME at all. Can’t speak as to how well modern versions of MAME compare to shmupmame, but shmupmame was tested to be extremely accurate in comparison to arcade settings, once you setup shmupmame right.


Ok good to know - thought I read it was tested there in recent years but if you’ve been there and not seen it then maybe not! Would love to go to evo myself at some point.


Well, I’m just saying the testing of modern MAME didn’t happen on the floor room. I’ve got no idea if people did independent testing up in their rooms or what have you, and I haven’t seen any mention of people testing is, so who knows? Would love to see the page where they talked about it if it did happen though.

Evo is dope! You should definitely go in the near future. It’s one of those hallmark experiences to have if you’re really into fighting games and the community.
