Re: AGD converted games: AEON series
I’m trying to run the AEON games on my DragonMMC, but they never finish loading... I am sorry to say that you will not be able to run any of these AGD games from the MMC (by now). I tried it and found that the module has not native support to emulate a Dragon Drive, instead it requires its own DOS ...

Re: Can just ONE byte be read from disk?
Hi Roberto Carlos, it seems it was easier than I had thought! Right now I have a ml program that reads the long file (screen definitions from an AGD program) and shows the data one row at a time on the text screen. Need to verify that the whole screen is shown alright (number of rows) and then the m...

Re: Can just ONE byte be read from disk?
Hi Roberto Carlos, it seems that I am able to 'open' the file and make it read sectors from assembler. It creates a FIB with a buffer area (256) so I could be taking bytes from there one by one and I must be controlling the end of the buffer in order to ask for next sector. This last part is not yet...

Re: Can just ONE byte be read from disk?
I think the smallest size you can read from disk is a sector, or 256 bytes. You can emulate getc’s behaviour by allocating a buffer, reading a sector there and triggering a new read from disk when reading the last byte from the buffer. Right, but this implies you know what sector you need to read f...

Can just ONE byte be read from disk?
Hello, I was trying to read the contents of a binary file but as there could be any value ($00 - $ff) reading variables / strings seems to fail ... Does anybody know of a trick to emulate the C getc function? Thanks in advance pere Pd The file is big enough to make it difficult to load it into memor...

Re: Reading a disk using DSKCON
Hi Ciaran,
I have tried your idea ... calling the same [$c004] but with command 1 (seek) when track changes
and then the normal command 2 to read the sector.
It works flawlessly, so now it is usable with any DOS, great!
Thanks a bunch

Re: Reading a disk using DSKCON
I think DSKCOM (CON?) is a fairly light abstraction of the actual FDC operations, so you'll have to SEEK ([$ea] = 1) first. right, it is DSKCON in the CoCo documentation, but is named DSKCOM in the DP5.0 comments Using this DP5.0 I have solved the problem calling $C167 every time the track gets cha...
