awesome work! looking forward to any details on how you recover their software

bsittler @bsittler.bsky.social · 26/04/2026

Not that I've found. The same circle's other works seem to get listed as PC88/PC98 simultaneous ones but I have not seen any listing with a date for this one specifically. Entry 3 on PC98 gets listed elsewhere as 1990 and I won't be shocked if 1 is 1988 and 2 is 1989, each dual platform (guessing)

i do think somebody put it in a Windows PC in 2021 but that just wrote a "System Volume Information" and didn't do other damage

i am leaning toward: disk is legit, datestamps are outright lies, and the atogaki in your disk that is missing from the LZH file is the clincher

010

bsittler @bsittler.bsky.social · 26/04/2026

i think it may be legit after all! those timestamps were bogus, the 2013 Wayback copy of the LZH file has future 2017 dates inside it?!?!? web.archive.org/web/20131104...

bsittler @bsittler.bsky.social · 25/04/2026

Answering my own question: it's basically the same. Even including some file timestamps from as late as... 2017. Same dates as in the lzh file. Maybe this disk got rewritten based on the downloaded version at some point?

bsittler @bsittler.bsky.social · 24/04/2026

cool! any idea yet whether the software version is the same as, or different from, the downloadable version on the author's site? www1.u-netsurf.ne.jp/~nori_koj/mt...

Somehow I failed to notice this got mis-auto-categorized into "Robots, Monsters & Space Toys > Robots > 1970-Now" - but it also has a bid on it, so I guess it's too late to fix that now. Ooops! 🤦

Did you ever wonder how people used BASIC on early home computers? One of the ways was typing in programs from magazines and running them! This recently launched site has tons of examples for many models, including Japanese ones but also models that were used all over the world code-recursion.tech

Also, I always fully fast forward then fully rewind tapes before playing them, it seems to greatly reduce the number of jams

bsittler @bsittler.bsky.social · 28/10/2025

I recently fished out a tape that separated from a cracked spindle and got tangled within the mechanism. Smooth coated wooden chopsticks worked well for gently untangling it. I reinserted it and taped the spindle and was able to read the tape and recover all the data. Sometimes it's salvageable!

So far on the Acorn side the only tapes I've finished converting are: - Chuckie Egg (A&F Software) (UK) (BBC Model B) - Hopper (Acomsoft) (UK) (BBC Model B) - Castle Quest (Micro Power) (UK) (BBC Model B)

bsittler @bsittler.bsky.social · 27/10/2025

not quite? i captured audio of some BBC Model B tapes as FLAC, and also made UEF. BBC-oriented tools I found seemed bad at audio-to-UEF so I used MSX tools to convert to MSX CAS format (more or less a "just the bits" solid image format) and then went from there to UEF using github.com/f-fix/cas2uef

that makes sense. the major differences start here, and for all i know may be where the data recovery went awry

The first two files (the loader and the loading screen) are bit-for-bit identical to the name-your-price version on tonsomo.itch.io/jurl-sinclai..., it's the third file (the game itself) where the differences pop up

bsittler @bsittler.bsky.social · 02/03/2025

possibly there is some audio dropout here?

bsittler @bsittler.bsky.social · 02/03/2025

Those have succeeded with both higher recording volume levels for the tape audio, and variants of the Kansas City Standard, which is a lot more tolerant of perceptual audio codecs and works fine even passed through fairly strict band-pass filters. The ZX ROM codec is a fair bit pickier

Given the label mentions PC-6601, I think this particular tape is likely from 1985 at the earliest. I have read that the game itself is a few years older than that, but clearly my copy of it is not

Japanese release was split across two HuCards. I don't know why, since on TG16 it was all on one card. This password transfers your progress from the end of Part 1 to the beginning of Part 2 (separate card, sold separately) and carries basic stats. A different password starts second part 1 pass 2
