That works for me.Thanks guys, i appreciate that!
Let me propose this: how about a fund in order me to buy an atomiswave cart from that guy, so after figure this out (almost close), we can discover how atomis games he made to work on the cart?
i'll put 25$ in my side of course.
Or if some of you having that cart is willing to "rent" me his cart in order to copy that?
I'll try to remove again proms from ikaruga taking some precautions, i will cover the proms somehow in order to only heat pins properly, i'm confident to have a good result.
I will share dumps of course
When i was searching around for info on this i found a blog with an overview of the conversion, donor carts and chis used. So that info might already be out there.That works for me.
If you end up with the desire to figure out how the Cave PGM conversions work, I would be willing to lend you the two I have in order to bring that understanding to the community as well.
its a standard header of ISO image.After trying to figure out what the problem was (if there was a problem), i have noticed this in the first IC, after scrolling some rows It's said right there, GDROM Jue (Sega Katana, that's the dev unit! cool)
uhm.. technically nothing@TheDeath what exactly you are trying to find out ?
if you are looking for rom board address space layout - me and @rtw already documented this a long time ago

iirc this link was posted already in this topic
nice, thanks mate. As i said, i've never been into naomi this far.@TheDeath what exactly you are trying to find out ?

its a standard header of ISO image.if you wasn't aware - many games store assets as such format, ISO9660 format chunk in IC1 and all the rest mask roms. while IC22 eeprom hold "game/rom header" structure plus "game mode" and "test mode" exe binaries.After trying to figure out what the problem was (if there was a problem), i have noticed this in the first IC, after scrolling some rows It's said right there, GDROM Jue (Sega Katana, that's the dev unit! cool)
I know what blog you're referring to, and it tells what's needed from a hardware perspective, but from the rom side of things it just suggests that you can figure out how to edit the roms by using the information within the MAME drivers. So either someone would have to work from the ground up and fix them to work on PGM carts, or someone could dump them. I'm sure among the community we have all three titles and could manage to dump them for everyone's benefit.When i was searching around for info on this i found a blog with an overview of the conversion, donor carts and chis used.

in game code only numbers is significant, last character is just B=board(PCB) or C=case841-0004B was converted to Ikaruga, the only reference I can find is for 841-0004C
Thanks man. Where do I donate?Pandora's (kind) opened.
First i wanna say thanks to all of you guys helping me out better understanding this cart conversion, i appreciate it.
What we came up with was basically the main rom-bin splitted, with little code editing in the IC22, the main header that any naomi(atomis converted) games have.
On this particular board (171-7919A) the "test mode" on IC22 was re-allocated in order to "jump" the unmapped area going from offset 0040000 to 0080000. That's the only difference.
Rest of the work was just based on splitting roms and burn them to the respective locations, that's it, no other code has been changed from the main rom.
To be simple, to make one, you just have to match the memory mapping from what the header is telling to, and that's the last thing i'm trying (we are) to came up with.
I'm making some trial and error with Dolphin Blue right now. I have successfully created the header with an hex editor but i have to reallocate the code for the test mode (just like ikaruga do). The naomi reconize the code but it's just stuck there cause i've not "telling" him were to look for the proms. I hope i can find this last and finally have an atomis game converted to a cart among with Ikaruga and maybe other naomi games like cvs2.
I don't think you are understand what you are actually doing. there is no need to edit any headers in this case, especially when you have no idea that's in thereI'm making some trial and error with Dolphin Blue right now.
