Aaah, it's that simple. Thanks Jim!

Hi all! Maybe someone can enlighten me! The TIs three main GROMs installed in the console are located at addresses 0x0, 0x2000, 0x4000 and are each 6144 bytes. So there are unused gaps in-between 0x1800-0x1fff, 0x3800-0x3fff and 0x5800-0x5fff. Now if I look at the bytes from a system GROM dump floating around the internet most of you surely know (994AGROM.BIN | 24576 bytes) the aforementioned gaps do not just contain zeros, there seems to be actual data. Now I'm wondering what is that data? Is it just some random bytes to fill-up the space (though I'm not sure what that would be good for).

Of course I did - it's refering to *.arc files not *.bin though so the confusion - meanwhile I figured it must be some kind of compressed format. Thanks for your effort!

Hi Lee. Well, I read quite a lot but this particular problem doesn't show up. The emulator doesn't really matter as I generally need to know how to run that TIFILES file from a disk image. With '.bin' I'm refering to the file extension of that particular file. If it helps, the game in question is posted on this site: http://tigameshelf.net/xb.htm 'Alien Landing' (Alienarc.bin) almost at the bottom of the page. I just noticed that there are actually two files in this file - I thought a TIFILES file is a single file only. A double-lick on the file inside TIDir reevals that there is 'ALIENBEST' and 'ALIENLAND' of type INT/VAR, INT/FIX respectively.

Hi fellow 99ers! It's ages ago I've touched a 99er and apparently I forgot the basics I stumbled across a website that hosts some Extended Basic games. Some are disk images and some are TIFILES and for some reason I can't get the TIFILES games to run. For example there's a game called 'Alien Landing'. The requirements say I need the Extended Basic cartridge and the executable to be run is 'Alienland'. Alright so far, I started TIDir, created a new empty diskimage and put that TIFILES .bin file into. One thing that popped straight into my eyes is that the TI filename is 'ALIENARC'. Anyway, I've 'mounted' the diskimage and tried to load it like: OLD DSK1.ALIENARC but all I get is an 'I/O ERROR 02'. After a deeper look at TIDir I realized that the game is of type 'INT/FIX' and not 'PROGRAM'. Unfortunately I really can't remember what that is and I'm completely lost! How do I load and run such a game? Furthermore what are those 'DIS/FIX', 'DIS/VAR', 'INT/FIX', 'INT/VAR' filetypes anyway? Thanks!
