PC Engine core

Postby Newsdee » Thu Oct 26, 2017 12:09 am

Sorgelig, thank you very much for porting this core. It's one of my favorite cores for the MiST and the changes to use BRAM fixed a weird palette glitch that I saw with many games (e.g. R-Type). Much appreciated!

Using core TurboGrafx16_20171025 and Mister_20180115 on DE10-Nano with SDRAM card (no I/O board)
I'm encountering some games that don't work or crash on the TG16/PCE core:

D&D: Order of the Griffon, music plays but only black screen
Air Zonk, no sound and game crashes shortly after start
Battle Royale, just black screen
Bonk's Adventure, corrupt graphics
Cadash, crashes after entering character name
Dungeon Explorer, crashes after game start with multi-colored flashing screen
Raiden, game freezes after 30 seconds of game play
Talespin, freezes right as title is about to start

All games mentioned above are USA roms (same roms work ok on Mednafen emulator)
Can someone else verify these games to see if they have any issues like I describe above?
Thanks!

I think there is a flag in the OSD menu that you can turn on before loading TG16 games.

Also some larger ROMs like Air Zonk aren't supported.

Also noted many games do not work. Blazing Lazers for one... It just plays the music, there is no graphic output.

Try loading the Japan or American version, usually one works.

Nope, Japanese version is "Gunhed" also with the same problem. ROM is fine, this is some issue with the core..

F12, then Load (...) not working?

Postby Bernd » Thu Jul 19, 2018 4:46 pm

Hi,

I am new to MISTer and wondering why I can't swap between different romfiles pressing F12 and then selecting 'Load...' for selecting a different ROM using the PC Engine core?
Instead of showing the file selection dialog nothing happens.
Is this only happening on my MISTer? Am I doing something wrong? It only starts a rom when I rename it to boot.rom.
Same happens with the Atari2600 while e. g. C-64 and Amstrad work fine: There I can change between different roms easily.

Do I need to worry or is this happening on your machine as well?

Thanks,
Bernd.

SOLVED:
On these cores you have to press SPACE or joystick button to start select. "Return" does not work. Sorry for bothering.

Has release 20180304 improved the stability/accuracy much? What percentage of roms are fully playable at this point?

I tested quite a few games and the vast majority run fine.

After Burner II crashes during the intro
Aoi Blink doesn't load (black screen)
Batman doesn't load (black screen)
Benkei Gaiden doesn't load (black screen)
Bomberman 94 has a blue line running down the right of the screen, but otherwise seems ok
Burning Angels has corrupted graphics
Bosou Keiji - Burning cross (black screen)
Cadash (freeze on Taito screen)
Champion Wrestler (black screen)
City Hunter (black screen)

I stopped there... There are enough playable games, but a fair few that still don't load. Feel free to test some yourself.

Thanks for the info. I'd test myself, but I'm trying to decide whether to take the plunge and purchase MiSTer + SDRAM board.

It looks like you were going alphabetically, so out of curiosity did Bonk's Adventure and Blazing Lazers work?

I was going alphabetically. At this point in time, I can't recall those two games, specifically. I did only rudimentary testing on most of the games. I'm not at home at the moment, and won't be until late Sunday evening, but will be able to check either late Sunday or Monday and get back to you. I'm reasonably certain I got the games from the TOSEC archive on the Internet Archive. So if the files are in there, then I may have briefly tested them and they worked.

Remind me to check the games in a day or two and I'll have a second look when I'm back in front of my MiSTER.

Bonk's Adventure loads but I can only see Bonk, the number of lives and the score. No level graphics are displayed.

Blazing Lazers only plays the audio and no video output.

Hope that helps.

Hey, thanks for testing. I didn't have either of those games in my original rom set on the microSD card. I've grabbed several different copies of the games and concur. Neither game works properly and displays as you've described.

Edit: I thought I'd test a few more games:

Coryoon - Child of Dragon - crashes starting a game
Cyber Core - black screen on start up, invalid graphics when starting new games, broken collision detection
Daichi Kun Crisis - black screen on start up, invalid graphics when starting new games
Darius Alpha - black screen
Devil Crash - Black screen
Don Doko Don - black screen
Download - sprites flicker but is playable (just)
Dragon Egg - black screen / frozen audio
Dungeon Explorer - graphical glitches

Ok, that's the D's done of the main rom set I have. There are a lot more playable games than unplayable, that's for sure.

A long time ago I made this spreadsheet for MiST:

If anybody wants to take over send me an edit request and I can add you to it :)
