Palace loader, an odd one for sure
I’ve already briefly discussed the fact that the “Palace” tape loader does not use timers for discriminating bit 0 and bit 1 pulses. What I wanted to do was adding some more information around the tape for “Barbarian II”. Side … Continue reading
How I went about defeating the tape version of Rubicon
Removing anti-disk-transfer protections In order to make a version of Rubicon that runs off two disks, I had to remove built-in protections designed to make things go horribly wrong unless the game is specifically loaded from tape and by its … Continue reading

Initial Coin Offerings (ICOs), MyEtherWallet, and EtherDelta
Update on the EtherDelta point below: Given the recent EtherDelta DNS attack, which took place on the 20th of December, I admit that it is NOT a good idea to use your primary ETH wallet in order to exchange on … Continue reading

Initial draft of the documentation about Palace Tape Loader F1
It’s an early draft, but I thought to share it nonetheless as the “Palace Tape Loader” uses a read bit routine that does not involve the use of timers! You can have a peek at the loader’s code here. Stay … Continue reading

Even more maintenance work in TAPClean!
Over the course of the last few days I managed to fit a few changes/improvements in TAPClean: I simplified the sync sequence matching logic in a number of scanners; I modularised the Tx scan in “Mega-Save”, “Freeload Slowload”, “Alternative SW … Continue reading

More maintenance work in TAPClean!
I finally found the time to do some maintenance on TAPClean’s code as per my TODO list. In short, I consolidated “Ocean New F1” T1/T2 and “Snakeload 5.0” T1/T2 scanners into “Ocean New F1” and “Snakeload 5.0”, entirely rewritten. The change … Continue reading

CHR scanner renamed and rewritten in TAPClean
Before bed today I decided to apply my field learnings about Mega-Save to the TAPClean scanner previously referred to as “CHR”, rewriting it from scratch. One nice addition is the decoding of additional information that’s part of the file header … Continue reading

TAPClean to support adjustable pulse durations
After inspecting some material provided by Pawel, I tested some experimental functionality in TAPClean that can automatically adjust pulse durations used to read/decode data within a TAP file. The idea is quite simple: usually pilot sequences seem to be quite … Continue reading
