Adding support for a modified NEOGEO game?
« on: June 07, 2021, 10:14:02 PM »
Well,

My buddy and I have not been successful adding support for a modified NEOGEO game using the FBNeo Libretro source. We successfully compile it and other games work but when it comes to adding our own - epic fail.

So was wondering if one of the pros would consider adding support:

Credit goes to Clear Paper for getting the edit done, we simply modified the p-rom to his specs.

From Clear Paper:
Blazing Star:
Enabling the Stage Select code was too much hassle so I made it default.

Along the way, I made other minor changes.
1. Level Select - adjusted alignment and colour
2. Stage Select - enabled by default, changed text, adjusted alignment and colour
3. Ending text - changed text to make it less painful to read

-----------------------------------------------------------------------------
The stage select can't be done with unibios and must be activated each time - this makes it default (like Pulstar) which I think is pretty cool.

I can submit the modified p-rom or whatever is needed.

Chris

That sounds pretty sweet, please pm me the romset and info about it / name of your mod / year made along with ppl to credit, etc and any modified fbneo source, and I'll hook it up.

best regards,

I guess its just inexperience knowing what all files we need to modify to add the driver.

we messed with d.neogeo.cpp

Hi,
I added your Blazing Star romset w/ name "blazstarcm".  Attached to this message is an IPS patch for everyone else to create the romset.

Tips for adding new roms:
I just copied the entry for blazing star, changed all the references to the new name "blazstarcm", tagged it with BDF_CLONE and set the parent to "blazstar" (second field in the BurnDriver structure)
Then I changed the crc for the p1 file and that was it :)

In the new romset (blazstarcm.zip) all you need to put are the changed file(s), it will automatically reference the parent se

Check the new code in d_neogeo.cpp for "blazstarcm" and compare it against the original "blazstar"


Here's the IPS file for blazestarcm:
