As far as cartridge rom support, I do like my MyIDE 2 as well, even if there had to be .R16 patches for the XEGS stuff. It runs every cartridge rom including XEGS that I've tried, even through my SpartaDOS cartridge. But .XEX support has a lot of holes and needs tons of patches still done for tons of software. I haven't tried ATR support on it, I think that is only through MyBIOS and MyDOS partitions though, I have mine setup for both that and SDX, and only use SDX. I use the FAT loader only for rom images for two reasons; one, that's all that will run from the FATloader through the SDX cartridge, and two, I can run .XEX's easy enough through SDX. If something is an ATR, I still just write those to real floppies and use my ultra-speed Happy 1050. But I still want the Cart! for all it's compatibilities, and because it has 512K sram on board that you can use ALL of, unlike the MyIDE 2 where 256K is taken for MyBIOS and you are left with only 256K usable sram.
You used my patcher in the past for XEX files, didn't you?
It has been a while since I wrote that patch routine. It was written in Synassembler, and I have LOST the source.
It is not rocket science, but it would be handy if I had the source code of my patch routine.
I have contacted Steven Tucker about this, and I think he would be pleased if I could tell him why my patcher works. I guess when he knows what my patcher does, it is easier for him to built it in his FAT32 loader.
I was on a short vacation and the only thing I brought with me was an Atari 800XE with a MyIDE 2 cart. Have had lots of fun. I was able to do some nice coding and saving, I was able to play games, I did write and save some TXT's. It is very awesome.
Only downsides of MyIDE 2 so far are: no RTC (IDE+ has it), no RESET button and the lack of APT partition table in MyBIOS. If people are ok with using third party OS's, then I would recommend MyBIOS in ROM and you will have a very nice harddisk interface.
My number #1 choice is still IDE+ ... especially the Real Time Clock and the fact that it is a real PBI device. It runs awesome on a stock atari.
SIDE2 + U1MB is awesome too. It is a very nice combination, with an amazing replacement BIOS written by FlashJazzCat. It is simply amazing. Downside for me is that it needs an updated atari and that I have to give up my cart port. But besides that, it is fabulous too.
So... choices choices choices....
