DoDonPachi Dai-Ou-Jou Black Label in Mame

[jonny5]

The wave is due to waitvsync or syncrefresh not being enabled.

^this

beat me to it.

Does enabling it add any lag?

no.

[joeboto]

check these inps.
does normal shot produces faster hyper meter than laser shot?
or bug?

Didn't realize I need the files from the original ddp3 rom. Just copy those and the 2 pgm bios files and it should work.

Do you mean copy them to the ddp3blk.zip? You don't need to do that. Just the PGM files will suffice (maybe not even those?). That's all I did anyway.

Well I had to. Had both of those PGM files and it gave me error about missing files. All those files were in the ddp3.zip, so yes I had to copy them from there.

We've got it covered and have already asked for that in private. I'm 95% sure it's fine for competitive play (i.e. plays the same way as the PCB does) as we've spent the last 48 hours figuring out supposed "issues" only to find it is normal behaviour. We'll tell you when it's ok, just note the scores down somewhere else for now if you're really concerned. The protection does not even affect half the stuff, but we've checked it anyway. Only thing that's hard to track down is standard rank, but we'll find it.

Anyway, it was as you said in the other thread -- actual behaviour. No protection calls were involved. I traced the code for the maximum hit loss by hand and I think I found the bug in the original ROM, I will be posting the disasembly later -- perhaps tonight if I can't get out of my insomnia phase.

If anyone can list off all the known strange behaviour of the PCB in the wild (with no dot, unlike the DOJBLEX port which has a dot after black) I would appreciate it.

i'm not overly concerned, just saves me a bit of time. the trouble is the game has two different rank systems in place, one that goes up through completing stages without losing a life or using bombs (and getting max bomb bonus); and another that's affected by hyper usage. and then on top of that it's things like speed issues, is the slowdown recreated accurately, etc. so in an ideal world i'd just like to see someone playing the emu version with a decent score no-miss no-bomb up to & including 1-5. but i hate computers and don't really wanna go to the effort of downloading the rom myself

maybe it would be easier if you tell me what you think are anomalies, and i'll tell you if they're present in the pcb or not

Is the stage 1 "berserk" attack (after destroying its side turrets) supposed to be a lot tamer in BL compared to WL? It feels a little bit odd in MAME, but I don't have anything like a comparison point, so!

If you read the strategy subforum. You would notice the WL/BL difference topic, yes BL is easier on first loop compared to second loop. That's because second loop doesn't remove your lives at start anymore.

[Aliquantic]

If you read my question, you would notice I was talking about one specific pattern on 1-1, not BL/WL in general let alone the second loop (but thanks, I've posted in that thread so I should hope I'm familiar with its contents!).

I've now checked the BL superplays and HFD still uses the "standard" WL strategy of damaging the boss until near death and waiting for a second revolution to destroy the turrets (at the cost of some time and danger), even though the berserk pattern isn't particularly dangerous on my MAME (compared to WL), so I'm a bit intrigued about that.

[powerfuran]

Yes, the attack you refer to is different in BL compared to WL. In BL it's easier to dodge, the bullets are smaller. Looks ok to me comparing the HFD superplay and the mame vers.

[Aliquantic]

Thank you

The wave is due to waitvsync or syncrefresh not being enabled.

^this

beat me to it.

Does enabling it add any lag?

Yes.

It might look a little worse, but 60 hz with no vsync/wait enabled produces the best results.

Running at native res on a low-res monitor this is not the case. It does not add any noticeable lag. Without it, the weird scrolling is very distracting. I am speaking from experience.

I can't speak for the kids running this on normal computers with all kinds of mame filters and stretching going on. But at native res, the wait for v sync is essential for proper display, and does not add input lag.

[Bananamatic]

Another question: Does st3 have less drones in the second half in BL? It seemed much easier than on the ps2 port.

[emphatic]

I can't speak for the kids running this on normal computers with all kinds of mame filters and stretching going on. But at native res, the wait for v sync is essential for proper display, and does not add input lag.

So, both "wait for vertical sync" and "sync refresh" should be enabled then, huh? I've been out of the MAME loop for quite a while, but I'm quite interested again now.

The wait for V sync has to be, not sure about sync refresh, but I usually enable it too; the wait for v sync eliminates that weird left to right scrolling/tearing in tate. To clarify, I am only referring to running this at 15khz at the native res of the game on a 15khz monitor. I'm not sure what effect or consequences it will have on a normal mame setup running on a VGA monitor with filters and stretching going on, or a setup that isnt running at 15khz at native res.

Cheers! I'm running these games in 640x480@60 to my UVC to my NANAO MS9 (my onboard Intel graphics card can't handle Soft15kHz) and I get lots of tearing/weird stuff at the moment. I haven't had time to fine tune it, just spent every available moment playing Ketsui.

Not sure how well it will work, but its worth a shot; I can't say how it will affect input lag at that setting though, I only play mame stuff in a cab at native res. On a side note, shoot me a PM with the specs on your mame setup and I may be able to link you up with a suitable graphics card for use with soft15khz. I have a drawer with a bunch of older graphics cards for when I do mame setups.

Yes, the old 'drawer full of random legacy parts'... shame it had to go when I moved!

[Aguraki]

thx!
this works perfectly for me.
I use 960*1280 60hz lcd screen vista 32 and a 3 year old computer.

ketsui works too.

[cools]

Use either waitvsync or syncrefresh - they both do the same job of removing tearing but do it in different ways. No need for both. As to which is better depends on your setup, try em and decide.

Well, what's the key as to which one to use? Is waitvsync better for d3d or ddraw for example, or what do you mean with "depends on your setup"?

[Aguraki]

can someone help me to find which resolution is best for me to play these games

DOJ/galuga/ketsui have 448*224 res and here my available res for my screen:

1280*720
1024*768
1280*768
1360*768
1280*800
1152*864
1440*900
1152*921
1280*960
1280*1024
1400*1050

I use 1280*960 for all 320/240 games (*2*2) but I can't figure a good one for ddp.
I think I can enter a custom res but it says it can damage my screen?

I use a LCD screen.

I mean "I don't care enough to investigate all the possibilities and provide an authoritive answer, and since it's a simple test anyone can do try them yourselves".

[autumndrone]

I use a LCD screen.

For 4:3 I use / d3d / cleanstretch 1 / autorol 1 / prescale 4 / hwstretch 0 / lcd nativeres / switchres 0 / filter 0 / scanlines overlay / etc..

2:1 (ket, ddp3, espgal) / d3d / cleanstretch 0 / autorol 1 / prescale 4 / resolution 1792x896x32 / window 1 / filter 0 / scanlines overlay (<bounds left="0" top="0" right="3" bottom="4" />) etc..

2:1 fullscreen / ddraw / cleanstretch 0 / autorol 1 / prescale 4 / lcd nativeres / scanlines optional if your cpu can handle it


edit:
Just to be clear, to use cleanstretch for d3d you must apply the cabmame patch first.

[Aguraki]

thx but do u mean change the res in mame?
or in screen settings?
can it damage my screen?

which version and where to get cabmame,and how to apply the patch?
if answer is in this thread just post yes

I had DOJ on PS2 emulator and it works faster in mame and takes less space(idk if the graphics are differents tho).

[system11]

When did the discussion of emulation stretch to 'OMG PLZ HELP ME GET MY ROMZZ0RZ WORKING OMG KTHX'?

Looks like I'm going to have to clarify that part of the rules, should be updated in a day or two.

[linko9]

Am I the only one who finds this game much easier than Galuda and Ketsui? I can consistently get to the stage 4 boss, and sometimes to stage 5 after just two hours or so of play. With the same amount of time put into Galuda, I can't get past the midpoint of stage 3, and with Ketsui, I rarely get past the stage 3 boss.

...yes

[HeLGeN-X]

Holy mother of god... Tears came out of my eyes after I just beat the first boss of Ketsui and encountered NO problems! Too bad I have to go to work in like 5 hours... I might take off from work due to this LMAO!

If anyone needs links, I will hook you up, but if it's against the rules, I won't.

Yeah, don't link directly to roms it is HIGHLY shunned upon. But any custom MAME builds (complete source code included, thanks emphatic) you are using are more than welcome in the MAME-specific threads.

For some clarification, look up a couple of posts at system11's.

Actually, custom builds without a COMPLETE source code link is against the MAME license. So that's in fact a no-no as well.
