Last post by NightWolve - Today at 12:28 PMHey naju and welcome!
Thanks for sharing! Not often someone would register for news on a new localization project!
Very interesting, I could swear this was one of the abandoned projects by TurboXray and BurntLasagna many years ago.
How did you accomplish all the variable width font work?? That looks very impressive, similar to what only Supper and TurboXray are able to accomplish. So you are totally new at this and your project has no connection or help to the prior attempt??
Wow, yeah, now that I looked at the screenshots I'm very impressed! Hope you'll tackle more PC Engine CD games in the future!
Once again, thanks for registering here to let us know. I appreciate the heads up as localization is something I've been passionate about since 2001 when I started the Xak III project!

Last post by naju - 07/29/2026, 11:43 PMHi all, I've made an English patch for the PC Engine Super CD-ROM² game Spriggan Mark 2: Re-Terraform Project. It's a horizontal shooter with an extensive story told through cutscenes and in-game dialogue.
The patch adds subtitles to the voiced cutscenes and fully translates the in-game dialogue, menus, descriptions, and other text. It also adds a small QoL auto-save feature to allow continuing from the last finished level from the main menu.
I tested it fully on a PC Engine CoreGrafx with a Turbo EverDrive Pro.

https://www.romhacking.net/translations/7662/
I do reverse engineering for a living but this is my first ever video game patch. Also I'm pretty new to this system but I just got my Coregrafx and I can't wait to play all the classics.
Anyway I hope you like it. Feedback/criticism welcome.
I'm also working on an English translation of the original Spriggan (Seirei Senshi Spriggan) for PC Engine CD.

Hello,
i've been working on this port of Doom for some time now.
t can run from anywhere from 10 fps up to 20 fps, this was captured on real hardware (from Composite).
This was not a trivial port to make, as the game encountered multiple issues (especially on real hardware) and i was forced to implement many things in my internal branch of pcfxemu to get it to run like real hardware (and even then, it fails to emulate the failures i encountered).
Download it here (assuming you have a copy of 3DO Doom sound track or your own) :
https://gameblabla.github.io/doomcpfx_generator/
Source code :
https://github.com/gameblabla/doompcfx
The port makes use of the following :
- VDC sprites for main doomguy weapons sprites. (Meaning its full resolution independent from the halved resolution for walls/floors/enemies)
- VDC/7up again but for HUD
- RAINBOW for sky (it's not scrolling currently. It's possible in theory but getting it to work on real hardware as it is, was painful)
- KING BG0 with internal resolution of 128x208.
- Supports CD-DA music and uses the 3DO version soundtrack (the tool will allow you to use your own soundtrack, if you prefer)
- KING ADPCM samples compressed to 8hz. It sounds generally the same but there are some differences.
Note that i did not try to convert the whole game : i believe that most people won't play beyond that (harsh but true), and this was a technical exercise. It's possible in theory, but the main problem remains with RAM consumption, as the game only has kilobytes left and nothing for weapons like BFG etc... This may require alterations but some uses like using CD DMA - KRAM - RAM bouncing to swap in real time if there's really no RAM left (that will also mean having to switch the music to ADPCM 32000hz instead of CD-DA). I haven't thought much about it yet.
Please enjoy it as it is.

The game has been fixed to work on real hardware alongside gameplay improvements.
Thank you all for appreciating the game as it is so far !

In most cases you have an opamp that is pegged (output pins near supply voltage or ground)

Ok the system has 3 sound sources
Chiptunes from the 6280 covers all card based audio
It's stereo
PCM audio used for high compression audio, often during movie scenes (depends on the game)
And CD audio (basic CD player sound from a DAC chip)
The 3 run through resistor/amp mixers

I'll let @thesteve know, if not @Keith Courage, the two main PC Engine repair guys that are reachable.

Hey everyone,
I recently recapped my entire Duo due to not having good sound or almost no sound from the console. It had also previously been RGB modded using doujindance's RGB amp mod.
Image looks amazing with SCART cable, same one used on Pc Engine CoreGrafx with no issues (sound n video great).
The sound issue:
- Full loud music through left speaker
- Only effects sounds from right speaker
I used console5 recap kit, so 50 odd caps have been replaced.
I've checked voltages on the IC506 and all sound I/O is 3.8V also checked C622 and that seems to be correct voltage.
Anything else I need to check?
Could it be as simple as dirty vias near/under the IC506?
Things to note:
- IC506 Pad 5 was torn so I made a jumper from a discarded TH cap leg from pin 3 to pin 5. Also ground pin 4 wasn't grounded so jumpered to the ground space next to it.
Could my IC506 simply just be toast? I did apply some heat near there so perhaps it got scorched?
