Space Manbow TurboFix

Here's a great new year's gift for fans of Konami's Space Manbow - and who isn't! It's a patch that improves two artifacts of the game:

TurboFix: Fixed the timing and splitscreen routines, allowing the game to be run with the turbo enabled on machines which support this. Running with turbo will allow the game to run at a much better frame rate and will also eliminate the constant slowdowns. Many animations also get much smoother, like for instance the animation of the bosses of stage 3, 6, 8 and 9. This patch will also enable the turbo on boot for turbo-R machines.
Fixed the bug of the random number generator of the stage 7 boss (the big neatly drawn green head with horns). This bug caused a long delay between the launch of each bubble, resulting in one of the lamest bosses in MSX history. After this fix, the boss starts to behave like a real stage boss.

@vanfanel

And it does support a turbo blitter too! Try enabling both the turbo Z80 and the turbo blitter on your DE1 and you'll see it.

My turbofixes are done in a way that the game will not be dependent of the slowness of any component anymore, even the VDP.

God job man!

BTW... did you test it on a real TR??... there are some glitches with sprites that don't appear on BlueMSX emulating a TR.

@Imanok

Yes, I tested it on the real Turbo-R too. The little sprite glitches are caused by the S1990 slowdown, as always. The effect don't happen on a Z80 turbo machine.

As Space Manbow have a somewhat buggy and very temperamental code with a lot of workarounds, I did chose not to interfere with it's sprite routines. After all, the sprite glitches are more than compensated by the smoothness of the game and the animations, isn't it?

What a pity

BTW... what's the difference between your turbofix version running on a TR and the original rom using the R800 (switched with the flashrom loader), in terms of speed and softness??

And one more thing... would it be possible to make a separate IPS patch only fixing the buggy boss?? (for people who only have an MSX2/2+ without turbo).

Why? Doesn't it run on those MSX-es?

Yes, my turbo fixes support any turbo machine, regardless of the brand.

Its just the auto-enable of the turbo speed that is restricted to machines that have the CHGCPU function in BIOS. To this day, only the Turbo-Rs have that.

Hello, sorry for revive this thread but i think found a bug i this patch.

In openMSX it works perfect but on a real TurboR it always hangs after the first game demo runs out. That is, if you let the game run the demo, the second time the Konami logo appears, the game screen turns black and the MSX hangs. It happends 100% of the time, tried with MegaflashROM & FlashJacks, the SHA1 of the game is: F6199F48FF994FC9A8E33A8581BB3BB16DD301AB

Which MegaFlashROM are you using exactly?

When I patch the game I get 1d995cf4521da949072344e8185c44744711f472 sha1sum. So something went differently...?
EDIT: ah, the original ROM image has the sha1sum you mentioned. Same for mine.

Yep Manuel, same SHA1 here after patching the required game ROM: 1D995CF4521DA949072344E8185C44744711F472

So you your TurboR freezes too after the game demo then?

I have tried many MSX machines, on my Panasonic 2+ WX it works fine, on my TurboR ST it works fine, but NOT on my turboR GT.

So it must be a problem with the amount of RAM the GT has? Don't know, but it freezes and i have to reboot the computer each time.

I only tried it on openMSX and indeed, doesn't happen there. But I tried with MegaFlashROM SCC+ SD.

Running it now on my real turboR using my Carnivore 2. The sprite issues are clearly visible, but the game crashes for me every now and then after dying... (yes, I do die when playing on a real MSX, quote a lot actually). Did someone else have this issue as well?

And yes, it also freezes for me after the game play demo, right after the Konami logo is shown and the screen is faded to black.

The patched version has the sha1sum=1d995cf4521da949072344e8185c44744711f472.

Can you please check of the same problems occur when you emulate the FS-A1GT on openMSX? (here it runs fine)

I don't have a GT, only two STs. One with 1MB and another with 512KB. Theoretically, the GT should behave like the ST with 512KB.

I wasn't able to reproduce it on the GT on openMSX. The sha1sum matches.

Very weird. It seems that the problem affects only some GTs, but not others. I asked a friend to test on his two GTs (with a MFRSCC+SD cartridge), and he could finish the game without issues...

Does the Carnivore2 have some way to force the SCC mapper for a game? Maybe the issue is that it's autodetecting the wrong MegaROM type.

بواسطة Manuel

Ascended (17503)

16-01-2021, 18:44

The game is running fine, with SCC and all. Just that the demo *always* crashes after the Konami logo and sometimes the game crashes after dying. If your friend skipped the demo and hardly ever died, he wasn't likely to trigger the issue.

SofaROM says:
ROM Type: Konami SCC
ROM boot address: 4033
Device: Carnivore 2 - RAM (that's the MegaRAM feature)
Device slot: 1-0
Device capacity: 720kB

Looks good to me...

Note that DRomero wrote:

So, it's not the Carnivore 2.

Oh, DRomero also already noticed it only happens on the GT, not on the ST:

So it must be a problem with the amount of RAM the GT has? Don't know, but it freezes and i have to reboot the computer each time.

And I can confirm this. @DRomero: do you also get the occasional crash after dying? It's like one in 20 times here.

Can you please check if the problem persists on the GT with the TRNEWdrv installed?

بواسطة Manuel

Ascended (17503)

17-01-2021, 19:45

I just did:
1. boot
2. install TRNEWdrv
3. start SofaRun
4. run the enhanced SPMANBOW.ROM

I let it run until after the 2nd konami logo and it still hung up there, as usual. Did not test the die-crash.

بواسطة Manuel

Ascended (17503)

I played and died lots of times, but I didn't get the crash now. Finally, after not pressing F5, I got the Konami logo again and instead of showing the title screen, I got the hangup. Seems it's effective not only after demo play, but also directly after normal play.

Perhaps there is some timing difference between the ST and the GT. We also noticed that when I play Xak ToG on my GT from CF (with the Carnivore 2) via SofaRunIt, I need to set up a disk delay, otherwise the graphics are mostly missing in the intro demo. But on Louthrax's ST he does not need that delay...

However, Wouter thinks the GT should be slower than the ST:

Quote:

ST is faster than GT IIRC .. related to memory refresh timings
i don't understand those timings yet, and this is only approximately emulated (based on the GT timings, but as I said, this is not 100% accurate yet)

So um.... weird?!
