Eeep. I had completely bungled the ASM for recycling sprites, it should be good now.

(Since this function was also used by the new slicing render mode, it's possible that slicing was broken for that reason)

Latest experimental:

Amiga:
* Fix for issue reported by @msmalik681, sliced images broken when off the left or right side

Mega Drive:
* Elements work on Mega Drive Parallax panels (which is to say, you can make your UI part of the parallax, like the screenshot).

I've published the initial source for my Protracker to MML (MDSDRV) converter under MIT licence, so that existing Scorpion projects can have their Amiga music converted for Mega Drive, there's also a prebuilt windows EXE under the releases tab.

This is only tested on JMD's music for Amigo the Fox, there's also a large number of protracker effects that aren't supported yet (also bear in mind only three channels can be converted, four channel MODs will need to sacrifice one channel).

Do feel free to send through MODs that don't convert well or at all and I'll see if I can do anything to improve on it. I'm also more than happy to receive pull requests that improve on the conversion process.

That is quite an amazing tool earok! Not had chance to play around with it yet but nice one all the same

Cheers! It's probably going to be quite broken until there's better support for a wider range of Pro Tracker effects, but I'm fairly happy with how it's going so far.

Did another update. Windows exe in the release section.

https://github.com/earok/pt_2_mml

Support for E6* (repeat) commands
Support for EA* and EB* (instant volume up/down) commands
Support for 9** (sample offset) commands
Improved handling of repeated sounds

Latest experimental fixes:

Issue reported by Mixel where setting x-speed to zero wouldn't work on CPU platform actors.
Issue reported by Master Linkuei where font loading could sometimes glitch on Mega Drive (all fonts and panels are now DMA loaded in the VBlank)

Ok, THAT now explains why the Rastan crescendo was shorter for BasementApe, it was not supported -_-

@saimon69 - that change log was for the Protracker->MML converter, not Scorpion Engine itself.

I take it the Rastan crescendo issue was when it was being played in the Rastan Amiga game?

Posted another update to the Protracker->MML converter

https://github.com/earok/pt_2_mml

* Support for 3 channel mods with "3CHN" header
* Support for E9 "Repeat every X tick" effect
* Rather than repeating endlessly, Macros are cancelled after one row (so effects don't run endlessly if they're not interrupted by other effects)

[earok]

Latest fixes to experimental:

AMIGA:
Fixed issue reported by Mixel where sprite parallax wasn't behaving well with actor sprites.

MEGA DRIVE:
Tweaks to panel loading, more of it is done with the DMA on the vblank. Hopefully this hasn't broken anything.

UNIVERSAL:
Fixed issue reported by Mixel where player vs actor collisions weren't triggering on a platform if the player wasn't standing on top of the platform.

Edit: Also an update to the protracker to MML tool

https://github.com/earok/pt_2_mml

* Support for mods that don't use set position effects to loop back to the start (songs are still set to loop infinitely by default).
* Fix for issue where samples that are either unnamed, or have the same name, could conflict.
