The 1541U Corner

Hi,

I'm wanting to replace the default cart rom with The Final Rom 0.8

The Final Rom 0.8 has been renamed to the default cart and I have replaced the file in the update1 directory. Now I want to flash the 1541U with the new information.

Carefully following the instructions and also following Gideon's fix. My Batch4 1541U cannot be flashed.

Any suggestions?

no, but this whole thread is a bit pointless, as everything has already been answered over there.

I doubt the forum has answers to every question, besides, I wasn't getting the answers quickly enough over there (as the forums are kinda slow) and this is where things are quicker.

Anyway, very interesting the 1541U has problems with Codenet on some levels yet not on others. Incidentally, Gideon is hoping to release 1.7 firmware upgrade in the next couple of weeks, it will include The Final Replay 0.8 ROM of which I sent him, maybe the upgrade will address some Batch4 concerns and possibly the Codenet issue.

okay, finally I have looked into my 1541u O:-), but I have problems. I have tried 2 c64s, one of them seams to be faulty, AR cart screen doesnt comes up when turned on, instead I get the blue screen with only 30xxx bytes free, and when installing firmware or in disk select, setup mode the screen is garbled.

now with the other c64, and two c128dcrs the problem is the same: cant get EoD and Desert Dream running. EoD: getting stuck at the very 1st change disk screen. DD: getting stuck on the 'depack screen'. I have freezed it in and its stuck in a loop waiting for the drive to do smth. Some other stuff seems to be working tho. Chuck Rock iffl loader & ScenePlus 2nd issue (irq loader) worked fine.

what am I doing wrong?

edit: oh and all tried also all firmwares...

I'd try the 1541-II rom, which seems to be the most compatible.

Then if changing disks doesnt work (it doesnt detect a new disk being entered), you can set the option for Remove SD = remove disk (or something), then at the disk-change screen you can pop out your SD-card, reinsert and then freeze and select the disk..

Everything works fine though with my 1.6.4 or the official 1.7 firmware. While you're at it, I'd put the appl.bin from Crest (from BluREU) on your card.

Dont forget to connect iec-cable on 1541U ;) Also its necessary to disable build in #9 drive for accessing sd-card directly, it messes most of the loaders if its enabled.

It doesn't. Talk to Clarence who did a HW-patch for that.

Sorry to push this "old" thread again...but I need a little tip:

I have always a reset-buttom in my user-port. If I press this one when I have the Ultimate-II in use, I will always get on the normal C=64-start-screen. No cartridge-screen (as I selected on the U2), no menue from the U2. The cartridge-screen only comes, when I restart my C=64.

(if I use the Chamaelon-64 it works - a press on the reset-buttom in the user-port and the Cham64-start-menue will appear).

Any idea why this does not work with the U2..??

Thanxx,


Mike
