It creates a tileset and tilemap, and in your case looks like it compresses both.

Here's what I do. Make a global byte somewhere in the assembly where you declare your variables (pasting this before ".section.keepboot" in sega.s will work). .section .data .globl vblank vblank: ds.b 1 Point the VInt vector to this. All it does is clear the byte. VerticalInt: clr.b (vblank) rte The...

Well apparently, --disable-multilib was what I was missing. Thanks for the link, forgot Saturn had one of those things too.

I'm having some issues getting any GCC newer than 4.x to build libgcc for SH. Gendev also had this issue if you tried to use a newer GCC than it used (4.8.6 I think) back when it supported 32X. The error: /home/grind/marsdev/toolchain/gcc-7.2.0/build/./gcc/xgcc -B/home/grind/marsdev/toolchain/gcc-7....

Overwrite your old sega.s with the new one in 1.2+

Do you have an include for "name_of_res_file.h"? Rescomp generates that header based on the .res.

Really cool stuff with the LTO, seems to work fine with Gendev as well with -flto/-fuse-linker-plugin. For those who still want to generate a symbol table: PLUGIN=$(GENDEV)/m68k-elf/libexec/gcc/m68k-elf/6.3.0 symbol.txt: MYROM.bin $(NM) --plugin=$(PLUGIN)/liblto_plugin.so -n MYROM.elf > symbol.txt A...

All global variables are loaded into RAM unless they are declared const. If you are using SGDK the boot/sega.s file loads that stuff for you on startup or a hard reset. I've never had to modify a SpriteDefinition, which rescomp creates as const (so ROM). There is probably a much better way to do wha...

Oh I see, I misunderstood how VDP_waitVSync works. I thought disabling interrupts might make it loop indefinitely, but the vblank flag it checks seems to be changed regardless.

I tried putting this into my title screen loop, and it doesn't seem to freeze the game at all (ate controller inputs though). SYS_disableInts(); VDP_waitVSync(); VDP_waitVSync seems to re-enable interrupts (or at least just VInt), so maybe it would be just fine to leave it the way it is, and call SY...

I had an issue in my project for a while where the game would hang between room transitions (fading). It would only happen on hardware, not emulators (except BlastEm) which reported Read from VDP data port while writes are configured, CPU is now frozen. VDP Address: 2, CD: 5 it looks like the proble...

Here is the usual algorithm for detecting if 2 rectangles overlap: if (RectA.X1 < RectB.X2 && RectA.X2 > RectB.X1 && RectA.Y1 < RectB.Y2 && RectA.Y2 > RectB.Y1) Your code is not taking the size of the rectangles into consideration, so the function will only set "Overlap" to true if the 2 sprites are...

Does the GDK environment variable end with a forward slash '/'?

And also GDK_WIN with a backwards slash '\'?

It looks like the tool is not adding an extra slash to the end when one doesn't already exist in the variable.

As far as I know the closest thing gennydev has to profiling is random gdb pausing and timing with Kdebug.

I hope I'm wrong though.

the modulus opoerator won't work right with fixed point numbers, have to convert to int first.
