Could you elaborate a little on this? Does this mean open the rom in a hex editor and swap the two bytes starting at 0x66 with the two bytes starting at 0x6A?Sly DC said:2. Swap two sets of bytes at address 0x66 and 0x6A of the program

That would be the only reason I would think where incompatabilty was an Issue.

Also, copy /b won't work for merging the C roms since they need to be interleaved. If I get some spare time at work today, I can probably throw something together to do that since I don't know of anything preexisting that will.
Byteswapping was easy enough because there's a tool on Eidolon's Inn that will do that.
Using an oversized Z80 rom may take some experimenting (and probably luck). For a 128K file, do you just truncate it at 64K or use only every second byte or what?
Sly DC said:Sprites (C):
1. Read two bytes from your C1
2. Byteswap the bytes from part 1
3. Read two bytes from your C2
4. Byteswap the bytes from part 3
5. Repeat steps 1-4 until your new rom is 4 Megabytes in size
A. Your output file may be smaller if your roms are tiny
6. Save the ouput file as spr.spr (Can be different)
Well that's all kinds of useful. Definitely got the whole kit.JMKurtz said:The homebrew dev kit that is on my site (www.neobitz.com) has a utility I wrote for doing all sorts of byte swapping, splitting, etc...
Of course, you can download the entire dev kit and write a game while you're at it
Got them already, and they seemed to be useless to me. Looked like they were more for making it work on an emulator. There's a tool in there that claims to make a CD of Pochi & Nyaa. Furthermore, they didn't seem to run on my Windows XP.Sly DC said:For those who want the tools that i took tomake the porting of MVS games,

I just used them to generate files for Puzzle De Pon R and it works fine in an emulator. Using those tools generated a slightly different prg.prg than following the instructions (I'm sure I just misunderstood them) and a completely different spr.spr than romwak did (word merge instead of byte merge, I guess).Neo Alec said:Got them already, and they seemed to be useless to me.

When I try to run the exe it just says command not recognized and closes.Murray said:I just used them to generate files for Puzzle De Pon R and it works fine in an emulator.

I'll give it a shot on real hardware tonight.
Edit: I'm using XP and the tools worked fine for me. They are command line only, though.

But the GFXCNV.EXE has a bug, it's been reported to iq_132 has he will release
a fix version for his GFXCNV.EXE. In the meantime, i'm using the NG to NGCD.exe
tool from SpekSNK (www.speksnk.es), which works great.
@ JMKurtz: Hi! Hope you don't mind that i did ports of Columns and Poker Night
for playing themon a real Neo-Geo CD system. If you want the ISO's, let me
know. I'll be glad to give them to you!

Sly DC said:Hi Again All!
@JMKurtz: Cool! So i have you blessing to post the ISO's "Columns" and "Poker Night". I"ll gather up a small Neo page on my web site with you two game, tools, the how-to...etc..etc... so that people can make their own ports and also play your two games on their real CD system.
@Fakk2: JMKurtz told me about the CDZ boot protection found in the IPL.TXT. Before replying to his PM, i took a look with a Hex Editor and seems that the protection is not included. Since i don't have a CDZ, i can't garantee that it will work on a real CDZ. So onced the two games posted on my web page, would you try to burn one of them and test it out ?
@Neo Alec: Weird...because for porting the MVS roms, i'm using WinXP but you have to open-up a command prompt (click on Start, All programs, Accessories, and click on the Command Prompt), after which you'll have a DOS prompt windowed and be able to put the command lines.
@For everyone who wants to make their own ports: the GFXCNV.EXE tool has a bug in it, me and KaNyEro reported it to iq_132 and the fixed version hasn't been uploaded yet. I'll put the NG to NGCD.exe tool (for swapping the C1/C2 files to SPR) on my web page. The tool is in spanish but it's very, very easy to use.
So keep an eye out for my Neo-Geo web page on how to port MVS roms to a real NGCD system. Onced finished the page, i'll post the URL.
Take care everybody!

a tutorial if you will, with a rom downloadable to a working cd
all tools and guidence
use a homebrew rom so we are legal
