Topic: Load game from Romdata

[xerf84]

Hello guys.

What is the idea of ​​this option?, could someone explain how it works?

Hi Xerf84,
I don't have a full understanding of this feature, but from what I understand so far, it allows one to side-load romsets that fbneo doesn't have yet in it's database.  Maybe taoenwen will explain better, as he added it

best regards,

Well, it would be good if he explained what the *.dat syntax is or what data goes there and in what order. I don't think the syntax is the same as the kawaks loader data, but the idea should be similar.

fbneo's romdata allows some romsets that are not on the list, but run with a common driver.

The format of *.dat is as follows:

Code: [Select]

///////////////////////////////////////////////////////////
// ZipName:  Zip names that are not in the game list     //
// DrvName:  Select which driver exists in the game list //
// ExtraRom: NeoGeo specific extra rom                   //
// FullName: Detailed name of the game                   //
///////////////////////////////////////////////////////////

ZipName:  cyborgforce
DrvName:  mslug
ExtraRom:
FullName: "Cyborg Force! (Homebrew)"

// romname romsize crc type
cyborg-p1.bin 0x0100000, 0x89e1c728, 1 | BRF_ESS | BRF_PRG
cyborg-p2.bin 0x0300000, 0xe4a8b27a, 1 | BRF_ESS | BRF_PRG
cyborg-s1.bin 0x0020000, 0x5bd29810, 2 | BRF_GRA
cyborg-c1.bin 0x1000000, 0x77078687, 3 | BRF_GRA
cyborg-c2.bin 0x1000000, 0xa5abdb83, 3 | BRF_GRA
cyborg-m1.bin 0x0010000, 0x06da3cec, 4 | BRF_ESS | BRF_PRG
cyborg-v1.bin 0x0800000, 0xdc50718c, 5 | BRF_SND
cyborg-v2.bin 0x0800000, 0x8135d5a8, 5 | BRF_SND

Cyborg Force! (Homebrew) as an example:

ZipName, the set we want to use, usually *.zip or *.7z.

DrvName, the driver we want to run from, it is recommended to use clone when possible, so that we don't have to prepare some ROMs that are common to the parent set;

FullName, well understood, the name of the game.

romname/romsize/crc/type，It's almost identical to the fbneo source code, and corresponds to the ROMs in our ZipName zip file, just write to *.dat.

The dat file can be saved anywhere we can find it, and romset can just be saved in one of the paths of the 20 recognizable ROMs.

After that, Ctrl+R, find dat and select it.

By the way, a graphical listing of romdata functions will be coming next to make it easier to use.
