Firmware 0.84

[marqs]

Firmware 0.84 released:

* Added 384×240 optimized mode
* Fixed audio infoframe content to comply with HDMI spec
* Improved 400p support
* Added default HDMI VIC compatibility option
* Remote hotkey and display improvements
** Enabled quick loading of profiles 10+
** Print profile quickload status
** Enabled sampling phase adjustment while in menus
* Added “Panasonic hack” for improving line count tolerance with line2x (certain Panasonic TVs only)
* HDMI AVI Infoframe VIC assigned for passthru modes (improved compatibility with Denon AVRs etc.)
* Added compatibility option for AV3 to use AV1 RGB and audio (enables Taito F3 AV1 connection with a small HW mod)
* Initconfig and profile versions made independent of fw version
* H. samplerate fine-tuning made more intuitive

Hurray!
Thank you marqs.

As a reminder, firmwares are available to download here, and the manual is here.

Line 5x stopped working properly for me after the update. Everything else works fine but 5x now looks wobbly no matter what I tried. Does anyone have any ideas?

I set up my PS1 and SNES profiles again and they look great! The 384x mode with my PS1works much better in 5x than the older method of using the 320x mode. SNES is limited to 3x mode for perfect compatiblity but it looks great still.

Hi,
the automatic input detection doesn’t work.
I have issue with sync in 480i passthru when resolution change . No issue in bob mode.
Thanks

You can try this alternative image which is compiled with different settings.

Can you elaborate a bit? Is this something that only occurred after switching to 0.84? Do you completely lose sync when changing between 480i and 240p? Which display you use and have you tried enabling “Full TX setup” under compatibility opts?

[Dextrose]

I forgot to mention that it was optimized 5x that stopped working but thanks, I’ll look into it later today.

[Dextrose]

Alright, optimized 5X works again with this firmware. Thanks for getting it out so quickly!

I don’t know when this started as I hadn’t done much testing with 0.83, but I noticed on 0.84, my SNES 1CHIP console is now very unstable on the sync (picture blacks out for several seconds at a time). It was never this way before, so clearly something was changed on how sync is handled. Anyone have some insight on this?

[marqs]

I don’t recall any changes in sync processing aside from Panasonic hack (if enabled), have you tried both firmware versions (default one and the alternative linked a few posts back)?

[FBX]

Apparently it’s not just me either. Had someone else message me they can’t get the SNES stable on 0.84 when it worked perfectly fine before they updated. Now I can’t claim to know if 0.83 had the same problem as I never got around to checking that one, but the updates before then my SNES was working rock-steady. Now I have to shift a bit out of phase to get a picture to hold on 0.84. Something had to have been changed during the past few firmwares for my SNES to suddenly become so unstable on the OSSC.

I’ll try the alt build, but the point is something got “fixed” when it wasn’t broken to begin with, so people shouldn’t have to use alternate builds.

[marqs]

These issues are likely to be caused by timing violations (rather than code changes) inside FPGA or on its boundary. The tools reported no violations with the initially released image so I have to re-check constraints, but in general it has got progressively harder to make a clean compilation run as more FPGA logic has been allocated for new features which leaves less liberty in placement & routing.

If the alternative build fixes the issues, I’ll replace the original ones with it.

Just wanted to give my input on 0.84a. Using my 1CHIP-03, with voultars rgb board/lpf off, using euroscart cable (Luma as sync) *should i get a different cable since csync is restored from voultars board?*

Anyway, I’ve had zero sync issues with 0.84a. Games I’ve tested.

Star Fox 1 & 2
Super Mario World 1 & 2
Megaman X
Street Fighter II Turbo (1 & 2 player)
Super Metroid

These are the settings I’m using on the OSSC for 0.84a, everything else is default from when I flashed the 0.84a firmware to the OSSC.

Video in proc:
LPF 9MHz
B/Pb G/Y R/Pr gains = 50

Sync opt:
Analog sync LPF = 2.5MHz

Output opt:
Line5x mode = 256×240 optim.
240p/288p proc = Line5x

Sampling opt:
<Adv. timing> 256×240:
Sampling phase = 90
H. samplerate = 341.00

Hi marqs,
any follow-up to this topic? I’m in no rush to update, so I’m wondering if it’s safe to grab the latest fw as it is right now, or maybe better to wait for a possible replacement? I own an original, no audio, OSSC.
Thanks! ^_-
