If that is really what he want then yeah, you don't have tools for that and honestly i think that results won't be good anyway. I tried long a time ago to make a tool which could convert a PCM sample (single sound obviously) into a FM patch (kind of). It's definitely *very* complicated to develop th...

Not sure what you mean exactly by converting PCM to XGM.
At least you ca declare your PCM resource as WAV resource then use the XGM driver to play it (whatever PCM channel you use for that).

Indeed, it looks like it eliminated memcpy from linking process (probably from the LTO optimization stuff) while it was required by the code. Maybe older compiler versions weren't using memcpy to copy structure while newer versions use it when structure size is > a certain limit (which explain why t...

Oh this one is a weird one ! i've no idea why it happen in SGDK 4.1 and not SGDK 4.0 though...
maybe related to linking ordering. I've to investigate that..
thanks for reporting

I completely missed your message @DavilaGames !
Indeed VDP_resetScreen(..) does more now than before (it also clear VRAM), explaining you need to re-upload the font after calling it.
Definitely a problem, i will add the (default) font upload to the function ! Thanks for reporting

You have indeed some limitations about the number of sprite you can use. The hardware itself is limited to 80 sprites max (H40 mode) so the sprite engine limit to 80 sprites max too. You cannot what you're doing : adding all sprites (using addSprite) for a level then hiding some of them until they b...

As usual, pure awesomeness !
Indeed i realized i already had the demo since several months but nice to see it having more visibility

Definitely very complex, as you said i guess it's someone with had already hands in GCC code. Even for 10000$ i don't know if i would have tried as i've absolutely no experience with GCC compiler code.

Oh ok, you did it

Good news

Developing SMS game is a complete different beast, do you know you have some tools for that :
https://github.com/sverx/devkitSMS

It allows you to develop SMS game in C, using a specific compiler and as far i can tell, it does work not that bad honestly

The 2 aren't connected but SEGA clearly indicate to always asserting BUSREQ during Z80 reset operation.

I tried to use u8 but remember it didn't worked for some reasons i forgot. I have to re-investigate it but almost certain it couldn't be done that easy :-/

Timer unit give a method to retrieve elapsed time from hard reset (SYS_getTimer() or something like that).
But SGDK also own the frame counter into vtimer variable.

Hardware sprite are limited to 32x32 pixels. Rescomp limit (meta) sprite size to 128x128 to spare ROM space on sprite metadata (hardware sprite position) so it could use s8 type to define offset and collision information. Having > 128 w or h sprites would require using 16 bit offsets for both hard s...
