New turbo loader: SetoLOAD

Alessandro Grussu · January 2017

For anyone interested in turbo loaders, here is my contribution: SetoLOAD, the fast loading scheme I developed for my Seto Taisho Vs Yokai game. It is available in two different versions, each of them coming in different variations.

All of the available schemes have been successfully tested on real hardware (48K, 128K, +2A) by feeding the input either from a PC playing TZX files with Tapir or from a burned audio CD.

SetoLOAD is freeware and can be used in every kind of project, even commercial ones. All I ask you in return is to mention me as its author.

Sample file loading (Multi version 1)

Full details, together with examples, sources and binaries, are available on my website in Italian and English.

Update:

New color schemes available for Normal version: black-cyan, blue-green/black-cyan.
Two new examples of practical applications.
In order to make code relocation easier, a reserved space has been added at the end of both Multi variations, thus making the first one one bit longer.
The highest possible memory address of all versions has been raised (up to three bytes for the Normal version).
Source file names of Normal variations now recall the border colors through the respective code numbers (0 = black, 1 = blue, 2 = red and so on).
Binary files have been eliminated.

This is cool, but how do you generate the file to load back in once you have assembled one of the sources?

(sorry for asking twice!)

Hi David, no problem, thanks for liking this piece of code of mine ;;)

As for your request: code blocks to load with any kind of turbo acceleration must be converted accordingly. Open the data block(s) in Tapir, choose "Turbo Speed" from the Block type drop-down menu, and substitute the timings values with those required by SetoLOAD, i.e.:

; Pilot pulse   2168
; Pilot length  3223
; Sync 1 pulse   714
; Sync 2 pulse   714
; Zero pulse     454
; One pulse      907

Then save the whole file as a TZX. You could also examine with Tapir the files I provided as examples on my website to get an idea of how it can be done, more so if you consider that with Tapir you can also view the data blocks content as disassembly.

Download Tapir from the mirror hosted on my website (the version on WOS is outdated).

Cool! ;)

By the way, can you check the link from Exolon?

Oops - the service provider has a problem with the "+" character, it seems. Problem now solved, thank you for pointing that to my attention.
