solution - Action Replay can work with Jiffy Dos in drive

This point:

LDY #$02
JSR $F82B

should be replace to

LDY #$00
JSR $F7E8

so in the bin file (CRT also) You must find bytes string:

A0 02 20 2B F8

and replace to

A0 00 20 E8 F7

and finally reprogramming EPROM (EEPROM, FLASH - I don't know what You have :) - maybe bin or CRT file to 1541U, EF... etcetera )

after this AR loader will be work with DOS or Jiffy DOS

Don't confuse this with SD2IEC - solution is for drive with JD

kind regards

I don't know every one JD an AR versions but a lot of AR bin have this JSR $F82B...

JD 6.0 1571

F82B LDA ($30),Y

it's OK

in JD 5.0 for 1541 disassembly:

F82B BMI $F856
F82D SLO $5A85

...

AR6.06 is clear - dont use $f82b

now what the hell is that now?

are you basically saying that old jiffydos combined with old AR gives problems, however using recent jiffydos with recent AR does not? *shrug*

1. Why You think "every one must used AR 6.06?" I use for example AR4.0 (made by polish factory Atrax V7.3)
2. Is the version 6 JD for 1541? I don't saw and I don't know so a lot of AR will be don't work with 1541 + JD5 i guess

However I'd check why my loader don't work with JD and notice this.

So - if You wanna my words:

1541 is more often used than 1570/71
every one not use "clear" AR
If JD 5 for 1541 is the final (I guess yes) version so look to point 2

the point is: you need to burn an eprom to fix this. and if you go that route, you can (and should) update to the latest version(s).

Yep - good tips thx

... old people like me - they are own habit (function keys, colors, menu) and I hate white menu, and don't know german...

that's why I still cling AR 4 :)

Anyway - maybe I'll try thx

This is actually very useful info, when trying to get the Atrax AR7.3 image working on an Ultimate with the JiffyDOS bins. Thanks Wegi!
