Covert Bitops Loader V2.24

Hi,
I released a new version of the Covert Bitops Loadersystem. Now it supports also 2-bit timed fastloader protocol, thanks to MagerValp for the 2MHz timing code!

I would be glad for any test results, both PAL & NTSC, and also exotic and multidrive setups. What it should support is:

- fastloading on 1541+clones, 1571, 1581, CMD FD, CMD HD
- "fake" IRQloading on IDE64 and VICE fast drive emulation (actually the test programs don't show whether this mode is active)

To test, use the examples.d64 and examples.d81 diskimages from the examples-subdirectory. Load and run either "EXOMIZER LOADER" (1bit protocol) or "2BIT LOADER" (2bit protocol) and see if it loads & shows a picture successfully.

Please also report if it did use the fastloader. You can see that from whether it clobbers the upmost 6 lines of the screen as it loads: if it does, then it's fastloading.

There was a problem with JiffyDos where the non-serial/fake-IRQ check would trigger erroneously (the detection code looks whether the zeropage location $a5 changes when doing I/O.) A new version has been uploaded over the old.

Cool, glad that it found its way back, since I used Covert Bitops as the starting point for my loader :)
