Re: Cumulus Preorder Thread

Re: Unable to create a DSK file with OSDK

As far as I can seen, not without changing the code:
http://miniserve.defence-force.org/svn/ ... /tap2dsk.c

Apparently your .FNT must be executable, which is why it got converted to .COM, but if it had not been, then it would have been a .BIN.

Re: Unable to create a DSK file with OSDK

It's a bug in the OSDK. Please try the following fix: - edit %OSDK%\BIN\MAKE.BAT - line 284, comment out the line with DSKTOOL and uncomment the line with TAP2DSK instead: :: :: Generate the DSK file. If OSDKFILE is empty we assume (hm hmmm) that the caller is packaging itself with floppybuilder. (W...

Re: Keeping labels between several pieces of code

XA apparently supports the concept of "label lists" that can be imported and exported: http://osdk.defence-force.org/index?page=documentation&subpage=assembler I never used that, but it's probably possible to compile your first module so it outputs the list of labels/addresses in a fil...

Re: Fast scrolling game howto, anyone?

Thanks Dbug! I will try to write something and provide some screenshots. About the loading screen just google for the loading screen of Uridium on the C64 and that's what I was thinking about... But better. I tried to come up with an image of a ship resembling the player's ship and converting it wi...

Re: Cumulus Issues

I guess the good thing is that we have at least now a large consistent baseline: The cumulus devices are almost identical (apart the two different display controllers), use the same components, built by the same person, and running the same code. The only differences are on the Oric side; which is m...

Re: Fast scrolling game howto, anyone?

On the sad side I am unable to come up with a nice presentation screen. Made different attempts with horrible results. Definitely I'm not a good artist :( Will try again, anyway. I (or other) can give a shot at, if you tell us what type of presentation you are thinking of :) I think it would be a n...

Re: Simulating a keypress in Euphoric debugger

What's strange is that if I do it in machine code (LDA $8C STA$02DF RTS), it has no effect when I call the routine. But if I execute the routine step by step with the Euphoric debugger, it works, the screen clears. :?: You meant LDA #$8C When you write LDA $8C it means "load A with whatever is...

Re: Track reading (Sedoric / FDC)

Can that be caused by the geometry? Tracks the closest to the center of the disk have a faster rotation speed than the ones at the periphery, so you can expect differences I guess. In that regard, I always wondered why we had a fixed number of sectors per track, it would make sense to me to have mor...

Re: Track reading (Sedoric / FDC)

Basically I guess what you need is to implement the equivalent of the 'diff' tools for your tracks: - Have 2 or more track buffers - Perform a complete read track in each of the buffers - Perform the diff to find the sequences of identical bytes Not trivial, but not impossible either :) You can also...

Re: Track reading (Sedoric / FDC)

It's important to keep in mind that these numbers of bytes are not fixed values. It depends of the format of the disk, and in particular the number of sectors per track. If you look in the source code of FloppyBuilder, you can find a bunch of commented sections with informations I got from various t...
