Yes. On active raster only (sun and background).

Jorge Nuno wrote:pin40 with the sun on screen? Nothing?

No signal. Logical 1 (actually 5v).
I want shematic diagram connections this pins on C2 machine....

Corrections: active only 120-123 pins.

Jorge Nuno wrote:At last LOL, and the pins?

LOL. There (on [120-127]) really have an VIDEO. And it remind an index of color. But on [18-25] still quiet. Maybe its activated on CRAM loads?
By the way: pins actived only on "sky". On text no moves there.
What do you think?

OK, finally it works.

Did it show the bios message? Or you have no bios? I'm trying to manually fix it... if that doesn't work then I will copy the init code Rom sent... I have an clone, that have no BIOS. That is correct, BIOS do init itself (TMSS), but most of clones have no BIOS. Second round... ***Not working. Can y...

It not starts. I guess you do wrong hardware initialization (or do not at all). I did same mistake, when began make own programms for MD. Do this: *Boot code move.l sp,a7 move.w #$2700,sr tst.l $a10008.l bne.s SkipJoyDetect tst.w $a1000c.l SkipJoyDetect: Bne SkipTable lea Table(pc),a5 movem.w (a5)+,...

The SE-93 is a pirate VDP, TmEE has one in his megadrive (check his website if you don't beleive me) I know this. Also SE-93 = TA-06; SE-95 = TA-04 + TA-05 and SE-95 = TA07 = YM2612. I just sent a rom to HwMan, so he can tell me what's on those pins, but I won't release it yet because i'm using the...

Tested pins [18-25, 120-127] in the same way. [18-25] - showed noise in the lower part VBlank, below raster (I have PAL console). [120-127] - showed noise similar to the noise of buses M68K. Nothing reminds raster. Just VDP has dividers of master clock frequency (I have models with 17,7MHz quartz di...

To understand how the VDP works, it is necessary to see how works the main component video system - VRAM. This Dual channel DRAM, incorporating feature is that the buses of address and data has been combined. The second port of serial access is connected separately. In order to obtain meaningful dat...

Fixed.

I have noticed that for every 32 raster pixels happening consistent with the reading of each Plan A/B and Sprites on 4x speed. Then, its shift inside VDP at normal pixel speed. Sorry but i don't understand what you are trying to say... :cry: :( OK. I will record live video to show you how it does. ...

Give me compiled PD-ROM with test and I will do some research.

Yes I can. I must check my PD-ROMs on real hardware.
