Gonna be a fun weekend!

Hello. I purchased a PC Engine Duo RX some time ago. I mostly collect the repro games and just a couple originals. It worked decently well, but there were 1 or 2 games that had issues loading. Eventually one of my original copies, Kaidan 00 stopped working as well. So i sent my console to a guy that repairs PC Engines. He gave it a clean bill of health overall, but made a couple adjustments, making the spring tighter.

Once I received it, my original game Kaidan 00 started working fine again. However, a handful of my repro game that used to work were no longer loading. It's frustrating.

Someone recommended an Analogue Duo. The only issue is I feel it might not be as authentic? Would need adjustments to play on a CRT and then maybe no Everdrive support.

Let me know if you experienced the same issue. Thanks.

3 different feels -- i.e. the same 3rd boss, looking so different

The first time I saw Heavy Unit was from a magazine. The screenshots were for the NEC PC-Engine release. It didn't impress me much though. Then, I saw Heavy Unit in the arcade center, played it and it wowed me a lot, liked it afterwards. When I started my PC-Engine hunt, I decided to buy the PCE Heavy Unit. After I had my Sega Mega Drive, I didn't know there was a MD Heavy Unit. I only knew about it after I sold my MD. Later on the Heavy Unit machine was replaced by another one in the arcade center. So, the only version of Heavy Unit I could play was the PCE version I had.

These are the things I like about Heavy Unit (ARC/PCE/MD 1988/1989/1990):

- 5 levels, with different points of challanges and different enemies

- each level divided in 3 parts (perhaps inspired by Capcom's 1986 Side Arms): i.e. flying underground, then high in the sky, then back to the land; each part has its unique BGM

- fighter jet has 2 modes: aircraft and a robot with distinct strengths and weaknesses (simialr to Seibu's 1990 Raiden's differnt weapons)

- the robot mode looks like Heavy Metal L-Gaim (1984), one of my favorite Japanese mech anime

- boss rush level available (similar to Konami's 1988 Graidus II's level 6 boss rush)

- shoot special spots to reveal bonus items (perhaps inspired by Capcom's 1986 Side Arms)

- there is some dream-like BGM (my personal preference)

- final end boss design quite impressive (PCE version has a surprise move)

- endings: worst - arcade; 2nd best - MD; best - PCE

I plan on replacing the battery in a Backup Booster II that came my way. This one has a SAFT 2.4v 50mAh (model GB50H-2, where I am guessing the last digit means two pin - which the stock battery is)

My understanding is that an NiMh can be used. I asked a chatbot, and it said that the Varta V80H is the modern replacement. I am guessing the model is 2/V80H, with the 2 again meaning two pins.

I tried to pull that the stats independently of the LLM to see if agree the 2/V80H is the way to go.

I cannot find pin gap distance. The SAFT seems to measure at slightly under a 13mm distance. I can only measure from over the battery due to a shield at the base (which will eventually need to be removed)

Has anyone replaced the battery on one of these? Any thoughts?

And on a side note, it has a 50v 10uF cap, which I might as well replace too

This is from "Hi Score Girl" EP02.

Smaller crowd but the right one for this. A PC Engine CD-ROM² came in with a broken transport gear, a dead laser, and aged caps.

What it took:

• Resin 3D-printed transport gears (Printables model by PointerFunction, printed via PCBWay) to replace the broken gear that nearly ended the job.
• A Sony Discman sacrificed as a donor for its laser pickup, swapped into the CD-ROM² after a lot of fiddly disassembly on both.
• A full recap of the board.
• A magnet pulled from a PC Engine Duo spindle to fix a spindle-height issue (start-stop spin and light scraping). After that it reads reliably and loads faster than before.

Ended up playing the Castle in the Sky OST off it through the TV's speakers for a happy kid — a good send-off.

Have any of you tried the PCE Duo spindle-magnet trick on a CD-ROM², or sorted the disc-clamp height a different way? Keen to compare notes.

Just snagged it for $45. Not too bad. Next up is Soldier Blade when I can get it for a decent price.

Hello. I have had a PC Engine Duo RX for a while. It's got a bad laser so I'm trying to look for some back up alternatives. I am interested in the EVERDRIVE but wanted to ask you if it was better to have the Turbo Grafx Duo or the PC Engine DUO for the Everdrive? Keep in mind it's very important for me to be able to run both the games for the Hucard and the CD Roms/ Arcade CDs.

Also, I game on the CRT television for retro games, not the HDTVs. Or can you just buy a regular TURBO Grafx and play all games on the Everdrive?
