Re: Looking for latest GEMS
Lord Nightmare , checkout this thread also http://gendev.spritesmind.net/forum/viewtopic.php?f=14&t=1898 plenty of useful info about GEMS. All you need to do to work with GEMS ROM is: 1) just very big RAM at correct location, 2) ROM from dev kit (that is in srecord format) at offset 0 3) gems lpt d...

Re: I'm officially building a microcode-level 68000 core
I wrote this program, dubbed "Schematic Explorer", which can directly load in the schematic svg, and allow you to rotate and zoom in easily, while also throwing in color, tooltips, dynamic highlighting of lines on mouse-over, and the ability to add custom comments and "annotation" overlays to docum...

Re: Algorithm for splitting sprites
Here is my ultimate version of sprites splitter. It's most advanced and expensive approach that I came up with so far. It's command line program. just run it without args to get usage. https://www.mediafire.com/file/fm111c159ietwnl/sprites_split.exe/file Ah. It reads from stdin, so if you want to fe...

Re: Algorithm for splitting sprites
If the image size is not 8-pixels aligned, it generates the 8-pixels aligned images, with an offset on width and height, up to 49 images (7 pixels width offset x 7 pixels height offset). Either description or your algo is incorrect. It should be 64 images 8x8 offsets. Anyone up to making testing of...

Re: aPLib decruncher for 68000
Yet another update of my packer. https://www.mediafire.com/file/22a2f2jzg2jfio9/aplib_pack2.exe It had stupid bug with if () .. if () ... instead of if () ... else if () ... Now it's fixed. It was hitting only copy comands when their offset >= 32000. Thus, if your file is less than 32000, it was nev...

ATM considering to keep it private or make it public.
I so shame about my eng, length, and lags because of compilation & stream.

Re: M68k opcode sizes test ROM
here also without bne.s start: http://www.mediafire.com/file/46op66mkn29uua8/m68k_opcode_sizes_test1.bin It's fine now on MED but on raw flashcart it still black screens ~80% of the time. I remember once my test ROM was failing because of bug in flashcard with size alignment. So, if without bne.s st...

Re: M68k opcode sizes test ROM
I just put common MD initialization, so I thought flashcart should not have any issues with it, because it runs many games very well which has similar MD initialization. Here is test new version: http://www.mediafire.com/file/jl2227tc4rk205k/m68k_opcode_sizes_test.bin Tell me if it fails or success....

Re: M68k opcode sizes test ROM
Nice!
Should I also remove warm-boot check?
Is filtering RESET passes test?

Re: M68k opcode sizes test ROM
I can't send compiled update one until I update it.
At this moment I don't know what to fix.
Can someone at least figure out why backdrop is purple.
It should not be so if VDP works correctly.

Re: M68k opcode sizes test ROM
EDIT: I've retried maybe 20 times with this flashcard and it worked 2 times to completion (2 green tiles), all other times just black screen. Maybe you're inadvertently using uninitialized RAM or some register? https://github.com/realmonster/smd_emu_tests/blob/master/m68k_opcode_sizes.asm#L217 This...

Re: M68k opcode sizes test ROM
I have no idea. Is it official MD? Normaly passed check is two green big tiles. All other results I consider as some bug, or flashcart issue. Screen should not be purple, It should be black with blue pixels in MD region. I setup palette at start, and never change it. And backdrop color is set to zer...

Re: Algorithm for splitting sprites
Your example is not sprite. It's just "idea" of sprite. So, I should make image first, and then feed it into my algo, then it will return list of coords, that I should also visualize somehow. Unless if I put it into ROM, then run in my gens mod, which may show sprite borders. All above requres some ...
