Release id #167152 : Krill's Loader, repository version 164

If no problems emerge (i know they will, but anyways)... I can explain a bit about the full on-the-fly GCR block read+decode+checksumming.

no, generated files in the repo are not an option either

(*) another requirement is that i can easily crosscompile windows .exe on my linux system. not sure if that rules out rust too - i havent tried this :)

Ironically that's probably easier for you than for me at this point; I used a Docker container running ubuntu so I could build the windows .exe for nucrunch; directly crosscompiling rust to windows binaries from macOS is currently nontrivial.

Quote: python has the same problems, i think (is it a single exe requiring no install?) (the point is: right now "our" dev environment is completely freestanding requiring no msys or cygwin or any of that, and no installing either - breaking that is not an option :))

the problem with ca65 are at least nucrunch and tinycrunch, those will not build.


tinycrunch requires no additional python libraries beyond the python standard library*, and indeed still works with python 2 - so for macOS or ubuntu no further installs should be required. Windows I've no idea.

Thanks for your ca65 bug reports re nucrunch and tinycrunch; I didn't realise newer versions of ca65 had made breaking changes.


(*unless you want to rebuild the test Koala, but I've shipped that)

IMHO, that's needlessly restrictive. While it's generally accepted that adding auto-generated files to a repository is a bad idea for various reasons, i find it perfectly okay to add files that are generated manually once in a while, even if they're generated from other code in the same repository.

maybe yes, maybe no :) i like it that way, and i am also exercising certain things there which i like to see elsewhere.

Really fast! But the loadertest-c64.d64 hangs with vice 2.4 on NTSC. Emulation problem or bug? (I don't have an NTSC machine to verify)

The option NTSC_COMPATIBILITY is disabled for the pre-built images and binaries (because it would slightly slow down PAL performance, see loader/include/config.inc). Enabling it should make it work with both PAL and NTSC.

Not that it matters in this case probably, but generally don’t report bugs / problems using 2yr old emulators.

2yr old emulators.
FWIW, 1541U (up to and including current versions) detection code as found in loader/src/install.s ;)
drvch1541u: .byte "m-e", .lobyte($0205), .hibyte($0205); read forward
            sei
            ldx #$ff
            stx $0300
            stx $1803; set all port pins as outputs
            lda #$a4; bit 0 may be forced to GND (1541-II) or connected to track 0 sensor (1541-C, normally 0 = not on track 0)
            sta $1801
            cmp $1801
            bne is1541u
            anc #$8a; and #imm, but no asl/rol, bit 7 of result goes to carry
            beq is1541u
            bcc is1541u
            txa
            arr #$7f; bit 6 of result goes to carry
            ror $0300
is1541u:    inc $1803; set all port pins as inputs
            cli
            rts
drvchkued:
If $0300 has a negative value after execution, 1541U detected.
