But I don't see how this would change things usefully in this specific context.
Neither I do.
The PPU's seem to have not being touched.
I got some pictures to try to explain better:
PPUs

CPU + Crystal

Hope this helps to properly understand what's up.

Re: SNES video problem

l_oliveira's advice was for modifying a Famiclone with a switchable PAL/NTSC PPU, not a SNES... Yes, in part of that thread it was, but that was so "dynamic" that we ended talking about SNES, MegaDrive, N64 and even PS1 transcodification. If I remember correctly you helped a lot too, with explanati...

Re: SNES video problem

How is the SNES syncing? It looks like you may need to adjust the cable to use Luma Sync. My bad! I forgot to say I was using composite video. In the transcodification, the main Crystal was changed for a 21.15366 one and this circuit was added to the BA6592F: 1K 2K2 GND <--/\/\/---+----\/\/\---> Li...

Re: SNES video problem

:lol: Actually it's part of the Contra 3 opening. Maybe I should ask holy water in Castlevania to try to fix the issue. :lol: This snes' case really needs a good wash, since doesn't just have that urine color, but also the smell. :( I'll try to add thermal paste to the 7805 before changing it. To ch...

Re: SNES video problem

Interesting. I discovered I added a little information to that thread but that was kind of poorly written, so I tried to clarify. I'll take a look on the 7805. I'll also try to get a proper crystal and undo the transcodification. Would an 74'74 plugged on the reset switch be enough to turn on/off th...

Re: Wavy Lines on NES-001 - but there's something more to it...

Sorry, I only saw this now, after over a year. :oops:
It was the on/off switch.
I think it sounds better and avoid confusion. :-D

Re: SNES video problem

Weird!!
I just removed the top shield to take a look.
It's on for about 30 minutes and this is what I've got:
tvtime-output-094420.png
Now I think it may be somethig that the shield is touching, since it's modified to work in PAL-M color system.

SNES video problem

Hello again. I got an "dead" snes as a gift. The PCB is a SHVC-CPU-01, S-CPU is a 02, S-PPU1 01 and S-PPU2 02. I changed the fuse and it turned on, but the video signal wasn't geting sync. I exchanged the electrolitic capacitors of the video outputs and the image looked fine, but after a few minutes...

Re: Any ideas on how to fix this SNES controller?

Thanks!
I'll try to find the Caikote 44 and also the dome.
I'll report back as soon as I have something.

Re: Any ideas on how to fix this SNES controller?

The copper is a little bit exposed.
I'll try to find some conductive ink and see if that makes it better.
I don't think micro switches are a good idea, is it?

Any ideas on how to fix this SNES controller?

Hi. I just got an SNES controller that the directional just don't move properly. I need to press it strongly, so I tried to clean with a small dry cloth. After most of the dirty has gone, I figured out someone else tried to fix it before, removing part of the contact's top: d8fbbd5d-5687-4ce7-af0d-5...

Re: Super Mario Bros 3 Controller handling timing

Interesting. I recently noted some random "pauses", just like someone had pushed start on player's 1 controller when playing SMB3 with the kids on a NES clone. Weird, that sounds almost just like the DPCM clock glitch. Maybe other games that use the DPCM channel will have problems? SMB3 (and any ot...

Re: Comix Zone: most technically impressive "16 bit" game?

I think the SNES can DMA tiles to VRAM to "amenise" this problem, not sure when or on what frequency.
Is it correct?

Re: Super Mario Bros 3 Controller handling timing

Interesting. I recently noted some random "pauses", just like someone had pushed start on player's 1 controller when playing SMB3 with the kids on a NES clone. Probably in this case there's something odd going on with the clone. I tried a pirate version of SMB3 and a original one with similar result...
