My CPS1 conversions info

No I'm saying use 27C4096G for the 3 program roms 21, 22 and 23. That's all you have to do. It's the easiest conversion ever.

So I was looking at the board.. and was like.. OH sweet capcom used UV chips.. I'll just back those up -- uv them and write rainbow to them.. after 30 minutes the chip didnt erase.. so back to placing my order for them.
 
Generally speaking it is best to keep the originals with original stickers and use other chips for rainbow (for starters, when you sell the board the buyer is going to prefer to have those chips and stickers intact). However since you already removed the stickers...30 minutes isn't a guarantee that the chips can't be reprogrammed, not at all. In fact there's very little chance that is the case. You have to have patience with those things. Most likely you need to use rubbing alcohol and qtips on the crystal covers on the chips until they are the cleanest thing you have ever looked at in your life. If there is any tiny little piece or dirt/grime/sticker glue it can stop the UV from completing its job and on top of that sometimes chips just take longer than others to clear.
 
Cheers.. I havent had any experience from erasing chips except a handful I ordered in to do cruisin upgrade with.. and that one erased really fast.. (about 20 min in UV)

I only removed the one sticker from the u23 - I have no intentions on selling the board - its one of my top 5 all time favorite games.. but again.. thanks for the tip!
 
I was bored and am still awaiting my GAL chips to arrive so I gave your Street Smart conversion a shot. It most definitely does not work with SF2CE PAL.
 
Of course it doesn't. The ST22B I said to use is from Final Fight. I guess you are confused that they didn't name the pal FF or something instead of ST.
 
No I was just curious due to the notes you had left and the PAL being unpowered figured it was some strange romset. Either way my GALs aret customs so won't be long :)
 
I used your GnG set and converted it to US version. Rather than paste roms here's how it's done.. first you need a script to interleave files. I used a perl script I found on the internet which worked great:
Perl: 
#!/usr/bin/perl -w

open LO, $ARGV[0] || die $!;
binmode LO;
open HI, $ARGV[1] || die $!;
binmode HI;

my $hidata;
my $lowdata;

while (read(HI, $hidata, 1)) {

   read(LO, $lowdata, 1) || last;

   printf "%c%c", ord($hidata),ord($lowdata);
}
close HI;
close LO;


What this script does is takes two input files and combines them byte-by-byte so if LO was 1234 and HI was ABCD the resulting file is 1A2B3C4D. Now if you look at MAME for CPS1 you will see the following for ghoulsu in the cpu section:

Code: 
	ROM_REGION( CODE_SIZE, "maincpu", 0 )
	ROM_LOAD16_BYTE( "dmu_29.10h", 0x00000, 0x20000, CRC(334d85b2) SHA1(89bacc28b7c799c7568420e3de5a99060baa7b0f) )
	ROM_LOAD16_BYTE( "dmu_30.10j", 0x00001, 0x20000, CRC(cee8ceb5) SHA1(fc8db1ce0c143dfda0b5989d02d5e5a872e27cd2) )
	ROM_LOAD16_BYTE( "dmu_27.9h",  0x40000, 0x20000, CRC(4a524140) SHA1(cebd651293c3570912d5506c1c223c39bcccc802) )
	ROM_LOAD16_BYTE( "dmu_28.9j",  0x40001, 0x20000, CRC(94aae205) SHA1(514b3c1b9b0b22300a94229825c3be66332ea5ed) )
	ROM_LOAD16_WORD( "dm-17.7j",   0x80000, 0x80000, CRC(3ea1b0f2) SHA1(c51f1c38cdaed77ad715cedd845617a291ab2441) )
These are the roms used to load the game. dm-17.7j if you did a comparison with daimakair after doing a word swap on dm-17.7j will find that it's the same exact file as damj_22.7f. This means the only rom we need to craft is damj_23.8f which are the dmu_* files.

Going back to the perl script we need to combine these chips into one big chip. You will see that the two roms are pairs - dmu_29 & dmu_30 as well as dmu_27 and dmu_28. Looking at the starting address you can see one is odd (ending in 0) and one is even (ending in 1). To combine the files is simple enough, running the script you do the following:

Code: 
./ans.pl dmu_29.10h dmu_30.10j > first.bin
./ans.pl dmu_27.9h dmu_28.9j > second.bin
cat first.bin second.bin > damj_23.8f
This will result in a 512KB file that can be written to replace the chip in socket 23 which will convert the game to US. For some reason it seems that the daimakair roms still have the English graphics so you don't really have to replace anything there. Same can be done for export/world just have to use the proper rom files.


You can also use the sound rom from the US which is what I swapped in, not sure if it's necessary. Just take 26.10a from ghoulsu and double it:

Code: 
cat 26.10a 26.10a > dam_09.12a
Write to a chip and place in the board and you're good to go.

Final Fight USA 900112 to SF2CE

You need the script above and two rom sets from mame - ffightjh and ffightua

From ffightjh grab s224b.1a and use jedutil from mame to convert it to jed format. This will be your PAL chip

From ffightua you need to combine some files to make chip 23:
Code: 
	ROM_REGION( CODE_SIZE, "maincpu", 0 )      /* 68000 code */
	ROM_LOAD16_BYTE( "ffu_36.11f",     0x00000, 0x20000, CRC(e2a48af9) SHA1(11e06f95bdf575af396dded2b84d858f6c7388f1) ) // in "30" socket
	ROM_LOAD16_BYTE( "ffu_42.11h",     0x00001, 0x20000, CRC(f4bb480e) SHA1(32114df1d2f4f98a4a2280a330c7b6af8ab4d862) ) // in "35" socket
	ROM_LOAD16_BYTE( "ffu_37.12f",     0x40000, 0x20000, CRC(c371c667) SHA1(633977c91a8ff09b7fe83128eced7c4dee9aee1d) ) // in "31" socket
	ROM_LOAD16_BYTE( "ffu_43.12h",     0x40001, 0x20000, CRC(2f5771f9) SHA1(fb532402bc00b5619a23dfa7e4525f1717020303) ) // in "36" socket   /* different CRC from ffightu, ffightu1, pcb verified */
	ROM_LOAD16_WORD_SWAP( "ff-32m.8h", 0x80000, 0x80000, CRC(c747696e) SHA1(d3362dadded31ccb7eaf71ef282d698d18edd722) )
Code: 
./ans.pl ffu_36.11f ffu_42.11h > first.bin
./ans.pl ffu_37.12f ffu_43.12h > second.bin
cat first.bin second.bin > ffu_23.bin

CRC(bd41c4e1) SHA1(16482fbac2b5396b2ff2f4645ec999a8f650a1d3)
ff-32m.8h becomes chip 22

graphics chips 1-4 (note might need to swap the location of 7m and 1m depending on if you have a MASK board):
ff-5m.7a
ff-7m.9a
ff-1m.3a
ff-3m.5a

ff_09.12b is chip 9

chips 18 and 19:
ff_18.11c
ff_19.12c
 
SF2CE to Area 88 Resale version:

Really easy conversion, it uses the same B board. You need area88r from Mame for this

GAL chip is "ara63b.1a" run it through jedutil in mame to convert to .jed and write

GFX chips for slots 01 through 04 are:
ara_01.3a
ara_02.4a
ara_03.5a
ara_04.6a

Note 2 & 3 might have to be swapped depending on if you have a MASK board

Audio cpu in chip 09 is ara_09.12a

Samples in chip 18 is ara_18.11c

Program 22 and 23 are:
araj_22.7f
araj_23.8f


Yeah that's boring and known information that could've been figured out with 3 seconds of effort. ¡BUT! UN Squadron US is actually hiding inside of area88r and converting Area 88 Resale to UN Squadron is extremely simple:
araj_23.8f
0x1327: 00->01
0x4564: 00->6A

These are two addresses that need patched within araj_23.8f which switches the game over to UN Squadron :) Just do those two hex changes, burn the chip and enjoy
 
Final Fight (900112) Region change.

On rom ffu_23.bin from sammargh, go to 7263A


00 - Japan
02 - USA
04 - ETC

If you set the Japan version, you need to create rom 1,3,5,7 from ffightj
 
Sure but it’d be a pain. Would have to split up roms and write a new gal and might have to switch some code if you don’t have a cp01 c board

Is there anyone that can put Punishier on my SF2CE PCB?

Punisher normally requires the CPS 1.5 hardware for music. There is a bootleg version that will work on your SF2CE but the music will be all wrong.

You may want to look into going the CPS 2 Multi route instead. There's a pretty good port of Punisher up and running on that hardware, plus a ton of other cool CPS2 games.

This is great. I assume you can do the same thing and make Strider resale too?

Probably... I paid apocalypse for that conversion though so I never bothered to look into it
 
Here's one I've just done, Varth JP Resale conversion to SF2 CE hardware: drive.google.com/open?id=1j3YHmM6UJeM63vwkxFKSVEvp22Ak7r5y

I did a file compare and found roms 22 and 23 in the resale are layed out like this:

(40 and 34 interleaved)+(41 and 35 interleaved)
(42 and 36 interleaved)+(43 and 37 interleaved)

I used the patched files from DBS and Porchys BINMan program to interleave and concatenate the files together to make new program roms. Hopefully someone finds this useful :)

If you have a mask rom B board use 27C400s and swap roms in position 2 and 3, rom 9 can be burned to a 27C512, place it on the rightmost pins in the socket. For 18 and 19 use 27C010s and 27C4096s for the two program roms 22 and 23. The va63b.jed file is burned to a GAL16V8D and placed in 1A, top left of the B board.

Hello guys ! I have a CPS1 Quiz Tonosama no Yabō 2: Zenkoku-ban (クイズ 殿様の野望2 全国版) board (CPS B-21 c board) .I don't know where to start, but i wanna to play another game on this board. What i must to do to make it possible ? It's any chance for me to learn & understand the conversion procedure ? I don't know what tools i need for this project and what i need to buy to complete a conversion, if will be necessary to do it ! ^^ Thank you in advance for all !
