Official shmupmame Super Turbo thread


Since not everyone have access to arcade ST, the best alternatives are dreamcast, HD classic and pc emulator.

Among these the best so far as agreed by many players is

(Download Shmupmame v4.2 Qt GUI + Command line 32 or 64 bits depending on your system)

If paired with a lagless display (CRT VGA Monitor or iiyama B2206 / E2201W / 2210), it can replicate the arcade experience.

I recorded a round in feilong’s stage using a supergun (US turbo 2) and the elapsed time is around 52.93 seconds (raw footage)

The emulator still runs a bit faster than arcade. With the stock emulator, the elapsed time is around 52.6 seconds

You can adjust the speed in the game property dialog

Using a game speed of 99%, the elapsed time is around 53.1 seconds (raw footage)

And if you set the game speed to 97%, the elapsed time is around 54.0 seconds.
Setting the speed slower is good if you don’t have a lagless display.

Configuring input

Once you start the game, hit [tab] to get into menu.

use arrow keys to navigate the menu, [enter] to select an item, [esc] to go back one level

select Input (this game)

press [enter] once on each input that you need to reassign, then press the button on your joystick once.
wait a second before navigating away to another input otherwise mame will record two input sequence for the same item.

Changing CPS2 settings

press [F2] to get into ST system menu and system configuration

if you are using JP version (grand master challenge), change it to turbo 3, otherwise use turbo 2

Training Mode

You can use cheat to practice combo if you want to get used to the timing for a tournament

put in the same folder as Shmupmame.exe
and enable cheat in game > misc tab

once you’re in the game, [tab] to get into the menu and navigate to cheat

turn on infinite PL2 & infinite time

the infinite energy cheat isn’t perfect, sometimes the dummy’s hit stun will be all screwed up, if that annoys you, you can bind an extra button on your joystick to toggle cheat on/off.


if you can’t get everything working, try /povpqngwrov5 on

I have done the nki input lag test with shmupmame using a 60 fps camera / lagless display. Results are below.

FGD Lounge: for general fighting game discussions that aren't thread worthy
Str presents: the st games @ evo 2013!

mame’s button mapping is kind of cumbersome to use in tournament

here’s a modified build with two extra menus

also you dont have to wait 2/3 of a second for mame to register your input

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.

Fei long stage time comparison


52.93 seconds


53.1 seconds

ps2 hyper street fighting

52.1 seconds

ggpo final burn alpha turbo 2

52.5 seconds

ggpo final burn alpha turbo 1

53.9 seconds

ggpo final burn alpha turbo 0

55.1 seconds

As you will find out below, final burn alpha has 2 more frames of input lag when playing offline on a lagless CRT.

2/60 = you are deprived of 3.33% of a second to react to any moves.

With turbo speed set to turbo 1, the game is 2.67% slower overall. But it still does not feel as responsive as arcade.
With turbo speed set to turbo 0, the game is 4.95% slower overall, you have enough time to react but your input will still come out slower.

And that was for offline with lagless CRT. Most LCD has lag. Also when online lag comes into play, you can see that playing at a slower turbo setting will be better.

pretty cool. Have you tried this on different machines? because I’ve heard the main problem with PC emulators is consistency in speed/lag etc… because hardware is inconsistent. That’s why my preferred offline alternatives are console solutions. Dreamcast / Console MAME.

but really I just lug around my arcade board and supergun :lol:

I would do speed comparisons myself, but I don’t have the equipment/knowledge to accurately time my arcade board vs PC on mame.

you have a guide?


If the performance is as good as you say then it’s a very nice resource to have. Eventually, arcades will be less and less accessible to everyone and the game will survive if we have a setup that is the same for both training and tournament environments. Fingers crossed.


Yes, it is assumed that your pc is reasonably powerful.
I forget to mention that I was using a i5 2500k with radeon 6800, which is overkilled for emulating cps2.

I tried the same test on a core2duo 2.4ghz laptop with a mobile 4 series express chip vga, the game play speed is the same.
Game play is 99% ok except when there are fireball slowdown + super, the vga is not fast enough to handle it.

Running it on macbook with 3rd gen i5 hd 4000 graphics it is as smooth as running it on my desktop even in tense situations.
I have no access to a 2nd gen i process with HD 3000 graphics but I assume that would also be sufficient.

Just make sure you have a clean windows installation and no malware adware antivirus heavy duty processes running in the background.

supergun and arcade board are easy. The problems are CRT and custom input. The latter can be solved with undamned’s cps2 but CRT will still be a big problem going forward.

Speed comparison is easy. Just recording the same stage on the same turbo speed and transfer the video to your PC (ideally 60 fps but 30 fps is ok).

Use media player classic Ctrl-G to jump to when “Fight” appears on the screen.

Mark down the seconds to the decimal place and do the same for “Time Over”. Subtract and you got the numbers.


Great to see this thread. I had brought up Shmupmame a while back but didn’t see much interest:



I can’t like this thread enough.


I thought MAME didn’t use the video card, all software rendering? So if that’s the case your video card isn’t the bottleneck.


Thanks for bringing this to our attention bro. I just had a quick round and it instantly felt better than the FBA GGPO uses. Night and day difference IMO


Shmup Mame is pretty cool. I use it for all my shmupping needs. Should be great for fighters as well.



Some good news. I did two tests tonight.

First using supergun -> crt, US Turbo 2

The crouching RH comes out majority of the time at 4 frames, with a few 3 and 5.
I would say the average number is 4

Raw footage here

The reason why the numbers are inconsistent is because of frame skipping

The 2nd test I did was crappy core2duo laptop with mobile 4 series express graphics output to CRT at 800x600 resolution. using shmupmame with 99% speed setting (everything else is stock) on windows 7 with aero disabled and mame running at full screen.

The crouching RH also comes out majority of the time at 4 frames, with a few 5.
I would say the average number is 4.3

I’ll do more test this weekend.
I plan to do

desktop i5 2500k with radeon 6800 => CRT
desktop i5 2500k with radeon 6800 => laggy dell lcd
2012 macbook => macbook lcd screen
core2duo laptop with mobile 4 series express graphics => laptop lcd screen

will keep you guys posted


Good stuff. Can you describe how you are getting the output from your 6800 to your CRT? Also, what kind of CRT are you using?



What we need to do now is what DGV and I talked about in a thread on here one time, and make a PS/2 Keyboard Arcade stick to avoid USB input lag.


soooo for us less informed, why would you use this particular emulator over regular mame? you can adjust the emulation speed in it too, in fact in the slider controls the main cpu is already at 74% by default, the significance of which i don’t know but if i crank it up to 100% the game speeds up quite a bit.


This version of MAME was designed by the shmup community for the sole purpose of reducing input delay. So for all intents and purposes, their version of mame works perfectly with what fighting game enthusiasts look for in an emulator as well.


The readme explains it best…


updated second post with a modified version of shmupmame with easier input mapping


Man, I headed down this path a little while back. Its not difficult to do, from a building perspective…BUT its difficult to locate a modern motherboard that has a ps/2 port that isn’t tied to its USB controller.



yeah. im waiting for undamn’s a board…

yeah. im actually stockpiling CRTs lol.

but really most lagless non CRT displays are really computer monitors. and I think there are plenty of Lagless Analog (RGB)-> VGA converters out there to use with ST boards…
