atr images - altirra vs atari800winplus

Recommended Posts

I have encountered a dilemma that I hope someone knows of a solution for. Roughly 10-12 years ago I created a few disks full of files on my 800xl/1050. I then diskcomm'd them and uploaded them via modem to my pc. At the time I was using Atari800Win/Plus on the PC. I used that to convert the dcm files to atr files. Several years ago I switched to Altirra after finding some glitches with Atari800WinPlus in Windows7, and seeing that Atari800WinPlus was not being updated/maintained anymore.

 

Just now I went to use one of those atr disk images in Altirra for the first time. Obviously there must be some differences in "atr format", because Altirra will not accept any of the atr's I created in Atari800WinPlus. I am however able to open and use them in Atari800WinPlus, so it's not the case that the files have become corrupted, but that Altirra just doesn't recognize Atari800WinPlus's version of atr. I have also tried using the PC utility MakeATR, but that utility also will not open the atr's, saying they are corrupt.

 

Any ideas? Any way I can either convert the atr's to a version that Altirra likes, or extract the files from these atr's and then import them into a new blank atr disk using MakeATR?

Upload a small sample of them, its easier to get to the route of the issue that way..

 

Also what version of Altirra are you on, depending on the version it may or may not know if its an Atr or stilll a dcm, Avery tweaked the checking code for xfd files that were named as atr's so it could be the same thing..

 

I recommend the very latest beta...

 

Newer versions do know the difference between dcm and atrs, I just checked..

Yep, turns out the latest version of Altirra does indeed read those old atr files. I was using a version from a year ago.

Glad to help, there are some emu's that are a bit rough in beta's but Altirra and Winuae are very strong in being better in beta that a lot of finals.

 

Nothing is ever perfect but i trust Altirra 100%..
