PC Engine ROM & CD Games - Grey Screen Upon Load / Does Nothing

ttmcmurry · 11 September 2019 05:02

Running Lakka 2.2.2, I’ve been having trouble getting a good number of PC Engine games working. The ones that do and don’t work seem to have no pattern about it. I have a working copy of syscard3u.pce for CD games. I also tried upgrading to the lakka nightly (build dated 2019-09-11) and have the same problem with the same images.

I’ve included the verbose log from lakka/retroarch. It shows the the “3 in 1” iso loading, bios is found and loaded, emulation starts, game pad input is registering (and I can see the text on screen showing the mode changes) but otherwise the game does not actually start, just have a grey screen.

The core in use is Beetle PCE FAST. The platform is Odroid XU4 on the XU3 lakka image. Any ideas what might be wrong here?

For example - (ROM)

Space_Harrier_(U).pce - loads, grey screen. Nothing happens.

Bonk’s_Adventure_(U).pce - loads, grey screen. Nothing happens.

Bonk’s_Revenge_(U).pce - loads, plays properly

For example - (CD)

3_in_1_DUO_Demo_CD_(NTSC-U)_[DUO_DEMO_01].cue - loads, grey screen. Nothing happens.

4_in_1_Super_CD_(NTSC-U)_[HCD2008T] - loads, grey screen. Nothing happens.

Shadow_of_the_Beast_(NTSC-U)_[TGXCD1018] - loads, grey screen. Nothing happens.

Try without auto load state.

I’ve been looking at this on a PC with the current version of Retroarch for x64/Win10, pointing at the same NAS store. There’s been somewhat better success with this on PC and I’ll agree the auto-load state is problematic when troubleshooting.

The documentation doesn’t do a complete job of explaining what is necessary. It only lists an MD5 to identify which BIOS image should be syscard3.pce. Turns out the emulator core expects all of the images, as listed, to be Japanese BIOS. Additionally, the docs also don’t explain how to add in (what to name) the US BIOS.

What it should read is:

syscard3.sys  - Japanese v3.0 CDROM2 Super System Card BIOS
syscard3u.sys - USA      v3.0 CDROM2 Super System Card BIOS
syscard2.sys  - Japanese v2.0 CDROM  System Card BIOS
syscard2u.sys - USA      v2.0 CDROM  System Card BIOS
syscard1.sys  - Japanese v1.0 CDROM  System Card BIOS

I’m finding the “point” releases of 2.x and 3.x are more problematic than what they’re worth. Also, the games appear to not be region locked to the country of origin. Therefore the preference toward the Japanese BIOS doesn’t have a material impact on the US released games I’ve tried so far, including home brew releases.

After understanding this through trial/error and Googling, did this work. The documentation is not complete enough to get this up and running, and doesn’t call out enough important pieces of information, and hasn’t been updated to keep up with the Beetle core’s development. Having to fork the wiki on my github to propose changes is another problem to tackle …

logically, i dont understand how that cant be “understandable” enough

syscard3.pce Super CD-ROM2 System V3.xx - Required 38179df8f4ac870017db21ebcbf53114

or anywhere related to the original problem.

It’s very vague. Use a 3.xx with required MD5. If you have a MD5 checksum of a specific file then it’s not a “3.xx” it would be a very specific version and localization. 3.0 would be different from 3.01 would be different between US and Japanese variants. It’s impossible to hunt for a file with that MD5 on the internet at large as no one posts “[BIOS] PC Engine SuperCD2 38179…blahblah.zip.” And if you’re going the legal route, acquiring enough physical equipment to dump the BIOS yourself and hope you bought the right one (again, no guidance in the docs for what BIOS you need, save for a MD5 of … something), then the task would be infinitely more difficult to find exactly what the emulator core wants.

I’ll reiterate the docs don’t explain the fact the Japanese BIOS v3.0 is enough. They don’t explain that the PCE/TG is region-free. They don’t explain how to also add in US variants. They don’t provide clarity in one read. Only if you know a great deal about a TG16/PCE, then sure it’s probably easier for you, but not for a newcomer to the platform and certainly not for a non-techie.

Once BIOS was sorted out, that answered my problem, and instead of getting grey screens, I got a PCE SCD2 3.0 boot screen. It may also imply the logging doesn’t clearly indicate the fault in the process despite it loading. Perhaps if the core knew more about specific BIOS releases and could self-identify the appropriate checksum including what the detected BIOS version was, and if it didn’t match a list of known good BIOS, then write it in the debug/log, but use it anyway … that, too would be more helpful. It sure as heck would have made troubleshooting far easier than making educated guesses + googling.

you missed that part probably. anyways the docs page is opensource and its maintained by non-paid, individual contributors. feel free add, modify or donate.
