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. |

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) |

Quoting Groepazno, generated files in the repo are not an option either 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) |

Quoting LazycowReally 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. |

Quoting JackAsser2yr 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. |

if only - 2.4 was released 2012 :)
thanks for pointing out the emulator code that can be safely removed :) |

Quoting Groepazthanks for pointing out the emulator code that can be safely removed :) If you mean the 1541U detection code, take a look at this option:.define ONLY_1541_AND_COMPATIBLE 0 ; reduces host-side install code by omitting any native custom drive code for non-1541 compatible
; drives, treats any drive as 1541, using an incompatible drive will cause undefined behaviour
