Add music and SFX to your BEX game with the XGM driver :)

Hi Davidian,

Sorry for the late reply, i have been very busy lately.
I tested your code and could not reproduce your problem.
Here's a rom generated from your BEX code:
dl.dropboxusercontent.com/u/93332624/dev/megadrive/test.bin

I modified the samples as i did not had your but you can heard that music is correctly played.
Also here is the compiled XGC file:
dl.dropboxusercontent.com/u/93332624/dev/megadrive/temp.xgc

You may try to replace your XGC by this one just to test if it comes from it.
If that is the case then maybe you have an older XGMTool version but it shouldn't affect playback in this way, that's weird

Hi Stef,

Just downloaded the last xmgtool from SGDK and now all works perfectly

Here a Stage Clear music www.dropbox.com/s/hbpopowgfef1qwl/basic.bin?dl=0

Drums sound awesome and the three test voices too.

Thanks.

[Stef]

Nice ! Glad you got it to work

[Stef]

I just fixed a small typo in the z80_loadDriver() method so for those who are using the XGM driver, be sure to take the last version of this method you can find here in the test.bex file:

hello Stef
i'm re-making all the sounds of my game with your XGM driver, and it works fine.
the sounds are very clean and it don't slow the game at all
thanks a lot !

Does the update fix the speed issue with PAL/NTSC?

Or if anyone knows how to convert TFM to VGM where it doesn't speed up on NTSC, that would be very helpful and useful for me

[Stef]

Hi Elusive,

Can you describe the problem you have exactly ?
You export from TFM to VGM then VGM to XGM and your music play too fast ?
And on which system you play the final XGM music ?
The XGM driver has one restriction: it plays music differently on PAL and NTSC system because all timings are frame based.
If the initial VGM file do not indicate PAL / NTSC information then i need to add a flag in the VGM --> XGM conversion to define the target system (PAL or NTSC). That may be the solution
That also mean you will have 2 different tracks for PAL and NTSC system (no choice here).

Hi Stef,
I used tfm to make the tracks and used shiru's vgm music maker to export to vgm. I don't believe there is a setting to choose NTSC or pal and I'm not sure if there's a flag for which region inside of the vgm file.

I don't mind having to use 2 sets of tracks for NTSC and pal

[Stef]

Thanks for the informations, indeed there is no setting for that. I think i only need to add a switch when converting VGM to XGM format to specify the target system (NTSC or PAL). Maybe something as "-p" for PAL system and by default conversion is done for NTSC system.

That would be most excellent if it isn't too much to ask

Hi,

In the information tab you can select PAL, NTSC or custom clock rate.

!!!!! I'm going to have to try this when I get home, thank you so much for this!!

[Stef]

That might help to change it but anyway i can add the switch in the VGM to XGM converter just in case the info is absent from the VGM file.

[Stef]

I committed a new version of the xgmtool to convert VGM to XGM file.
By adding -n or -p switch we can force to "NTSC" or "PAL" XGM conversion.
Here's the last version:

Unfortunately, the NTSC setting didn't help any. I tried saving as VGM 1.5 and 1.6, but neither helped. Trying the new xgmtool now
