1541-III beta firmware release:

Sorry for the long delay,  the project suffered from technical difficulties. The compiler has troubled us with a nasty by easy solvable bug. Thanks to the persistence of Jussi, this was finally fixed and now we can continue with new releases. The previous beta release of the Jiffy-DOS 1541-III firmware had a problem which caused lot’s of files to fail from running properly. This is fixed and games now load as expected. But with the speed of Jiffy-DOS.

This beta release of the 1541-III firmware holds lot’s and lot’s of new features. But the most important feature of it all also makes it the most useable version of all 1541-III firmware releases. Why, because it supports JiffyDos. JiffyDos consists of a fastloader that makes all disk access much and much faster. Making the use of your precious commodore much more fun.

For those who are not familiar with the JiffyDos, just google, otherwise, thrust me. It’s really usefull. JiffyDos speeds up ALL your disk access. Programs or games without a fastloader used to be slow… but suddenly they become as fast as… “greased lightning!!!”. So enough about JiffyDos.

Why is this release a beta release,  simply because this release holds a lot of changes made to the 1541-III’s firmware, very crucial changes. Most changes are not noticed by the user, and some are never used. But I won’t go into detail.

This release is usefull for those who want to test JiffyDos on the 1541-III. It’s functional but not yet finished and it needs to be tested… by you!

So please feel free to report all found issues so it can be solved.

PS: this beta-release was made possible by Jussi S., he was the one who took the initiative to integrate JiffyDos support into the 1541-III. The other changes to the firmware were done almost a year ago, but were never tested enough/stable enough to be released. His enthusiasm to integrate JiffyDos into the 1541-III has given a new boost to the development of this project.

PPS: future releases will no longer have sound samples to produce the sound of authentic disk activity. However, synthesized sounds produce some sort of feedback. This was required for freeing up programming space for the Jiffy-DOS routines. It was a matter of fun versus functionality. And functionality has won.
