1.10.3 OK 1.11.0 KO

[josete2k]

After the Near's splash screen the sd2snes freezes or have graphical glitches and freezes...

Back to 1.10.3 and it's all ok again.

1CHIP PAL supercic snes (LM78S05 regulator too)

REVH modded board.

1.11.0b1 same issue

[josete2k]

1.10.3 working

[mrehkopf]

Wild. Can you run the diagnostic firmware (https://sd2snes.de/files/sd2snes_diagnostic_firmware.zip) and attach the entire log? You can find instructions for running the firmware at https://sd2snes.de/blog/cool-stuff/sd2snes-diagnostics
The new firmware depends more on a specific clock signal from the SNES and I want to check if it arrives at the FPGA properly.

NOTE to anyone else reading this issue: the diagnostics I linked is only for the OG sd2snes.

A year ago I had the same problem where the 1.11.0 beta would start up corrupted or just a black screen but I could run 1.10.3 and play basic non extra chip games. Turns out that my caps where just starting to go bad and I was told the 1.11.0 version actually used more power even just at the menu and that is why it had more problems.
A full capacitor replacement fixed all my problems.

You could have the same issue. Assuming you just upgraded the regulator and left the original caps in.

[josete2k]

I can play every extra chips (yoshi's Island MSU too) in 10.3

I only replaced the regulator. But, do you Really think that it is a capacitor issue? I'll take a look if this issue cannot be solved by software...

Thanks.

[mrehkopf]

It could be related to the whole save state logic running along, now triggering some underlying defect; unfortunately your diagnostic log is incomplete, it is missing part of the SNES memory test and the test summary. Did you wait until the LEDs made a running light and the screen turned (hopefully) green?
But the clocks are listed in the log, I think they are a bit high but I need to confirm with reference values.
It is a Brazilian SNES, correct?

[josete2k]

I don't have leds but the screen went to yellow/Green so I supossed that the test was finished.

I'll repeat in a few moments.

It's an eurpoean pal 1chip snes

[mrehkopf]

Oh, was just guessing from the unusual system clock (21.45MHz).

[josete2k]

Well... That's maybe because the supercic mod (with 17.734476Mhz Crystal and a 21.47727Mhz Crystal), isn't it?

Can you check if the v1.10.3-frs firmware https://github.com/furious/sd2snes/releases/tag/savestate_v12
or the https://github.com/RedGuyyyy/sd2snes/releases/tag/usb2snes_v11 works?
Both need to be installed over an existing v1.10.3.

[josete2k]

Yes

[mrehkopf]

Could you try this FPGA bit file? Just overwrite your original fpga_base.bit in your sd2snes folder with the one from the ZIP file. (Only for OG sd2snes and no expansion chips for now)
Firmware v1.11.0 needs to be installed first.
fpga_base_new_address_sampling.zip

[josete2k]

I'll test it tomorrow.

Thanks in advance.

Nothing. Black screen.

[mrehkopf]

https://sd2snes.de/files/sd2snes_v1.11.0-testsampling.zip
Can you extract this over your current v1.11.0 installation (so that fpga_base.bi3 and fpga_base.bit are overwritten) and try if it works better? This basically brings back the old sampling as it was in 1.10.3.

Sorry for the later reply

It works!!! But some games like Batman returns PAL show the region warning: "this game is not designed for your console"

Same rom is working with 1.10.3

SuperCIC enhanced ON
menu 60Hz
game auto

I've tested with menu 50 and game 50 and same issue... the console remains at 60Hz in game even menu is 50hz

[mrehkopf]

Oh, try this fix: #186 (comment)

(Auto region patching doesn't seem to work well in some cases; I suspect that wrongly dimensioned parts are used on some old cartridges. This might also be causing the original problem that you reported in this issue. Could you post some pictures of your cart?)

Working...

I've mixed https://sd2snes.de/files/sd2snes_v1.11.0-testsampling.zip and https://github.com/mrehkopf/sd2snes/files/10765998/issue186.zip and it seems that's all ok.

[josete2k]

It's a chinese cart with the mod to rev H

[josete2k]

[josete2k]

This is the pcb that I used with magno for sdd1 tests and there were some issues with sram files on it (issues you fixed in the past)...

[r0g1nh0]

Thank you very much mrehkopf and josete2k, my sd2snes rev F was not saving the games or playing the audio of the MSU-1 games and with the combination below, everything started working again.
