Post subject:  Retro Replay ROM 3.8 Load Error or what?
While I was putting this little PRG together called ShowMAC (find it in the files section) I was testing it with different ROMs to make sure it would work. I discovered that when loading the PRG from the Retro Replay ROM it had 2 consecutive byte errors at $088A and started wondering. Well.. I'm still wondering, that's why the program has 20 NOPs in it ;-)

The weird part is that I can make that loading bug go away by putting the RR in the MMC64 pass through, boot to MMC64 BIOS, press F7 to exit to BASIC and then F7 to Install Fastload.

Anybody know of this bug?

Just to be clear: RR with RR ROM 3.8P inserted. Power up, hit F7 to install fast load. F3 to get dir, then load ShowMAC with F2. Go to monitor with F8 and look at $088a and $088b. They are both #$00 but should have been #$EA.
Not all code I make loads wrong, so why does this?

Is this the infamous CPX 3.8 Load Bug or is it perhaps a new one? But IIRC the old bug was supposed to be fixed in 3.8B/P so this must be something else then.. :?:

I seem to recall someone mentioning something about some loader issue fixed in 3.8b too, but well.. memory is a bit fuzzy nowadays ;-)

Does someone have a bit more info about the bug that was supposed to be fixed?

The loader bug was fixed by me. Other things I have changed according to my history list (dunno if it is really in there, can't check as I can't find my RR at home :( )


In other words.. we don't know if the fixes are really in there :shock:

Argh.. forgot about this bug when I made SetMAC ;-) ..so SetMAC won't load using Retro Replay ROM. (if you really need that, I'll fix it)
The interresting thing is that I cannot load SetMAC using the Boot-to-MMC64-Press-F7-F7 method... :shock:

Do you mean you first load SetMAC, then do the reset dance, and then SYS to start the program? In that case try removing memory card before reset.

No I mean regular load using Retro Replay. It can load ShowMAC correctly AFTER doing that "Boot-to-MMC64-Press-F7-F7". All other situations, Retro Replay load fucks it up. With SetMAC I cannot load it at all with Retro Replay.

This is very strange indeed.

1. Did you try loading from within the Monitor?
2. Does you program include a BASIC stub?
3. What addresses do you load between?
