Re: Horizontal HIRES and Text scrolling code needed.

Based on your description, the easiest would be to scroll vertically, maybe something like barrel rolls, like the old style dispensing machine in gas stations: You can easily smooth scroll vertically at full speed, without much memory overhead, something that is hardly doable horizontally. That woul...

Re: Horizontal HIRES and Text scrolling code needed.

Does it has to be HIRES? If you can afford to have a repeating pattern, you can do some fancy things, like the wobble effect in Barbitoric which is 100% TEXT mode. http://defence-force.org/pages/demos/barbitoric/pics/barbitoric_6.gif Also using TEXT mode you can use double size characters, which hal...

Re: Oric DSK Manager

And yeah, my copy of the SEDORIC manual is definitely getting dog-eared at the moment .. all the commands I should know, feel I should be an expert on, but in actuality I have no clue about. Do you have an actual english version of the manual? On the library I only have the French version (and not ...

Re: Spam and Inactive users

You're welcome :)

I'm trying my best to make/keep the whole DF thing in the way I would like many places to be, with a reasonably good signal/noise ratio, no name calling and community fight, free sharing of information, etc... I admit that sometimes I lose my cool on some topic, but I'm trying :)

Spam and Inactive users

Thanks to the manual registration, the forum has avoided a massive wave of spam, since Saturday morning about 150 accounts have been created but they stayed inactive. What I did is that I changed the "captcha" question on the registration page, and I mass deleted all the inactive users. What that me...

Re: INSERT MASTER DISC IN DRIVE A

Sorry, I was gone for the week-end (family celebration thingy), I'll take a look later. I did try to patch the .h already a few days ago, but it did not work, I guess I fumbled when I did it. For reference my version looked like that: Line 265: 0x49,0x4E,0x53,0x45,0x52,0x54,0x20,0x4D,0x73,0x74,0x20,...

Re: Oric DSK Manager

Do you think that loading the three patch files one after the other, instead of as a merged one, would still work fine?

Re: Upgrade Time: Encounter

I managed to find a bit of free time for a new video, this time I worked on the replayability of the game by adding a high-score table.

Re: Horizontal HIRES and Text scrolling code needed.

HIRES scrolling is generally a very context specific operation, and ultimately it depends on a number of factors: - How much memory are your willing to use - Do you need to scroll the entire HIRES screen - Does the scroll area contains attributes or not - Do you use some backbuffer (or work directly...

I guess we could just extend the TestSuite with a few programs to test these cases. http://miniserve.defence-force.org/svn/public/pc/tools/osdk/main/TestSuite/ The idea is the following: :: :: The idea is to run each of the OSDK tools to generate a particular set of data, :: and then check if the re...

Re: INSERT MASTER DISC IN DRIVE A

The version that comes with Tap2Dsk *is* a master version, else the SYS, INIT, MOVE, etc... commands would not be working. Do you know where I can find a patched version of Sedoric 3, or at least a version of Sedoric 3 with the patching routine, known to be working? If you find one, I could update t...
