So,I've done my homework, and indeed, I can write at 0x70!!
Tested on Fusion and real (PAL) hardware.
Unfortunately, it looks like it doesn't work on Gens.
I can write 0x70, the KMod debug window tells me it has been modified,
but when H_INT happens, it looks like it goes to 8802A2 no matter what ...

Multiple scaled 32x32 sprites ~150 sprites

These results are just insanely great.
I’ve been working on 32x 2D for a long time, and what you’ve achieved totally blows my mind!
Congratulations to you.

By the way, regarding editors, you definitely should get in touch with segatim
The guy just issued two brand-new games in cartridges. See the demo subforum here viewforum.php?f=8

Wow that’s two brand-new games in less than one week? What a great time to follow Sega Genesis scene.
Congratulations to you!!

Great achievement. Congratulations!!

That one hurt because it's true and it applies so much to me :lol:

Didn't mean to hurt you.
We're hobbyist. It's very easy to start a game, a bit less to get a proof-of-concept (that's usually my stop), very hard to get a game almost finished, and insanely hard to have an actual game.
Hence the ...

It's a great question.
Steam may be a solution.
Moreover, there have been a bunch a new - great - games that have been published quite recently. I would suggest you to get in touch with their editors. I bet they would happily ship another good game.

But, if you ask me, it's a great question that ...

This topic, and everything you have discovered so far, is nothing short of amazing!!!
Congratulations to you!!!

I've done some testing regarding private RAM (cache used as RAM), and how it compares to cache-through SDRAM.

My code is something like this :
main:
ADD #2,R2 ; R2 = counter
AND R3,R1 ; R3 = Address Mask. M: $3FFFF ; S: $C00007FF. Not needed for 16-bit tests

BRA main
MOV.W @R1+,R0 ; R1 = Read ...

done some testing on a real PAL 32X, and FILL is ~36% faster than ASM loops.
Your mileage may vary.

Glad it helps ^^

That's exactly the stuff I want to try next.
Beforehand, I would say that the FILL is a bit faster than a well optimized loop, but I'll have us the numbers ^^

Hello to you all.
I've been toying around with the VDP FILL function, and especially, trying to trigger it again while already filling.
Here's my code:
MOV.L !AUTOFILL,R4 ; $20004104
MOV #LINE_WIDTH,R0 ; 40 pixels
MOV.W R0,@R4 ; Set Length
MOV.L !FRAME_BUFFER2,R0 ; $24000200+128*FB_WIDTH
SHLR ...

It was just something like this :

All right, by looking into Sega SDK\SEGADTS\32X\DEMO\SOJ_32X, I could achieve something (well, I sent a byte from Master to Slave on real Hardware).
Here's the stuff:
initMaster:
* ...
MOV #$80,R4
MOV #74,R5
MOV #$20,R6 ; TE | SCK is output
