When you have that kind of weird behavior you can be certain this is just an edge effect and that the bug is somewhere else. That's the problem with C code, you don't have any protection against illegal pointer / index access so it could work until you change something completely not related but whi...

Myself, even if i don't use it much i would recommend Tiled as it's a nice software to draw map and has many features as including scripting to build custom export format. Right now SGDK still lacks of a good map management system, this is my next big feature i want to add, and i will probably direc...

it's the sprintf(..) function which doesn't support long type (u32 / s32), even by using %ld unfortunately.
You can use intToStr(..) method to avoid the problem (note that intToStr(..) is limited to [-500000000..500000000] range)

SGDK HInt handler is definitely slow when you need to do a specific task at each scanline... The interrupt process itself consume up to 44 cycles + ~124 cycles (just quickly did head cycle counting) for the ASM wrapper + 16 cycles for RTS from C routine means that you have ~184 cycles on the ~484 av...

Well in fact you have a way to encode priority information into the image but you need to arrange the palette properly. So you need a 8 bit image (indexed so) where : // b0-b3 = pixel data // b4-b5 = palette index (4 palette max) // b7 = priority bit So you can see that bit 7 can be used to store pr...

Look like you updated SGDK by copying new files directly into the SGDK folder.
The problem is that some removed files (as vdp_pal_a.s file) weren't removed from your src folder
Just remove vdp_pal_a.s file from src SGDK folder and recompile the library, it should be fine

That looks really awesome ! I tested it very quickly (without all shortcuts so i was limited) but so far it seems to have all features needed to compose music on the Megadrive. Very well done =)

There is no real way of doing that automatically yet unfortunately. To disable looping you need to set sprite->timer to 0 when you're reaching last animation frame (setting timer to 0 actually disable auto animation). Also to change animation speed, again you need to set manually the sprite->timer v...

I think that is an interesting project :) When i was looking to develop my "PCMtoFM" tools i started to read some scientific literatures about it. I found some interesting articles but never got to time to investigate them in depth unfortunately, at this time IA or genetic algorithm weren't as effic...

One way to translate PCM to FM would be to treat it as a seq2seq machine learning problem. The training sets could be generated by generating random sequences of FM commands and the corresponding PCMs; then the model could be trained to do the reverse mapping from the examples. Interested in experi...

Oh no that is something completely different here, the tool you show just convert a WAV/PCM to PSG data taking in consideration the PSG constraints to filter/process the PCM data and obtain the best quality out of it (from the PSG). The resulting PSG data size is close to the PCM data, it's just dow...

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
