De-protected PGM games

I want to ask here if anyone knows it. I have seen in MAME that Demon Front jamma "all in one" boards have a V107 Korean version, around a year newer than the cartridge versions. They are worth to buy for the possible improvements these versions have / the price difference from the cartridge version?
 
I haven't made any direct comparison but when i asked the question some time ago the answer i got was pretty much it doesn't matter for Demon Front. (The Gladiator has the wrong music on the PCB version & the Spectral VS Generation PCB isn't the Version preferred/used for tournament play)

So, it wouldn't matter to buy the Korean jamma PCB that normally costs around a half of the cartridge only version, and it sums it has a PGM mainboard included, so the final price of the game itself would be even lower
 
All i can say is i bought a All in One Pcb version from Korea and so far I'm happy with. If you're interested in something specific i could test it if you like (I'm not sure about the exact version of my PCB without plugging it in again)

According to mame, if your main screen of the game says V1.1 below the big logo, is the V107 Korean version

I only wanted to know if there was any big issue or bug that was fixed in this version

No there is no known differences between 107KR and previous versions, besides the hardware implementation used (Cart vs motherboard / game single PCB). You can buy the cheaper KR version and patch it with a file that IQ created to have English text too.

Can someone tell me if this version of Dodonpachi Daioujou dual is the definitive version for fluffy's cartridges? My doubt is because in this site says is BETA version

it is stated as “Beta” because just in case is any bug mentioned to be fixed by @iq_132 , but wasnt the case so far . nobody reported bugs or gliches for this version , witch is great 🙏🏻
 
Another question. Is it possible to make Dodonpachi Daioujou dual boot without the IGS PGM system intro? I mean, booting directly to the disclaimer message as Espgaluda and Ketsui do, but in this case directly to the menu for selecting White Label or Black Label.

Yes. The ddp3 bios is intro-less. You have to fill the first two megabytes with copies of the bios, then the second half with the ddp3 rom. There are jumper settings to make it boot at address 0 and use a 4mbyte rom. Hopefully this makes sense.

I'll try it today. Doing this I shouldn't have problems, right? I mean, is necessary the IGS PGM bios for something?

I think only exchanging the first 1MB where de PGM BIOS is with the 1MB DDP3 BIOS should do the trick, because the DDP3 GAL16V8 is prepared in the 4MB CPU for loading the game on the last 2MB and the bios in the first 1MB, so I will let you know

Alright, I think what's needed, but I'm not good with python and the correct files to use. @iq_132, could you please create a dodonpachi dual version, but instead of using the IGS PGM standalone bios, the Dodonpachi bios?

Simply putting it on the P1 eprom doesn't work.

I can test the binary with no problem at all.
 
Yes, you're right. The first 1mb should be bios, then the program rom. Sorry about that. I'll try to put something together tonight.
