_Fandal_ Posted November 7, 2008 Share Posted November 7, 2008 Hi all! Have you ever heard about "The 1 MB Raytracing Animation Demo"? It was written by Stefan Springer ages ago for MegaRAM III expansion (banks controlled by registers $D301 and $D600 plus independent Antic access to XMS). This week I modified it for all pure $D301 expansions (banks $Ex, $Cx, $Ax, $8x, $6x, $4x, $2x, $0x). It was tested on 1 MB expansions by Satantronic and by Pasiu (many thanks to tWh and Bob!k). Modified version can be found here. Enjoy! F. 1 Quote Link to comment Share on other sites More sharing options...
Beetle Posted November 7, 2008 Share Posted November 7, 2008 Cool, Fandal! Finally, another 1MB Demo i can enjoy on my 1250XLD. Thanks! Beetle Quote Link to comment Share on other sites More sharing options...

Rybags Posted November 8, 2008 Share Posted November 8, 2008 It works fine in the emulator. Just the disk numbering doesn't quite correspond. Disk 1 side 2 = disk 2, disk 2 side 1 = disk 3 etc. Press console keys to pause the animation. I'm guessing here it's just flipping through static frames? Would be interesting to have the same effect done in APAC or TIP. Quote Link to comment Share on other sites More sharing options...
Poison Posted November 8, 2008 Share Posted November 8, 2008 (edited) Yes! Fandal you are really the greatest !!! Impossible in a minute, miracles in three days. Deflector, many cart hacks and game modifications ! ReSpEcT ! Edited November 8, 2008 by Poison Quote Link to comment Share on other sites More sharing options...
Mathy Posted November 8, 2008 Share Posted November 8, 2008 Hello Fandal Did you just replace the addresses used in the code? If yes, could you please tell me how often you had to change a number? My own upgrade uses the 26AE rows of banks (x1 to xF). Greetings Mathy Quote Link to comment Share on other sites More sharing options...
_Fandal_ Posted November 9, 2008 Author Share Posted November 9, 2008 Hello Fandal Did you just replace the addresses used in the code? If yes, could you please tell me how often you had to change a number? My own upgrade uses the 26AE rows of banks (x1 to xF). Greetings Mathy Hi! Loader and main part of demo were completely dissasembled and compiled again. New banking was done by simple table but main part had to be relocated from $4000-$8000 memory area as the demo used independent Antic access. I think I can try to make a version for your banking but I need more information. You said that your upgrade uses banks $x1-$xF. Is this correct? I would expect $x0-$xF as you need 16 banks in four rows to have 1024 kB of XMS. Anyway, if you use LSB for banking, which bit is used for switching OS? In other words, I need to know meaning of all bits of $D301 register in your expansion. F. Quote Link to comment Share on other sites More sharing options...
Mathy Posted November 9, 2008 Share Posted November 9, 2008 Hallo Fandal My upgrade uses the bits 0, 1, 2, 3, 6 and 7 for bankswitching. If either bit 4 or bit 5 or both go low, the status of BASIC, Selftest, (Missile Command on the XEGS) and OS is frozen. But the OS, BASIC, Selftest and Missile Command are still selected with the same bits as before I put the upgrade in. Greetings Mathy PS my upgrade still has separate ANTIC and CPU access. Which was the main purpose of developing it. Quote Link to comment Share on other sites More sharing options...

Stefan Both Posted January 17, 2015 Share Posted January 17, 2015 Sorry for pulling that tread out of the graveyard. Is anybody able to make a single atr file of that demo? It would be perfect to have the demo as a single file. Even with a Sio2SD, it is a pain in the ass to load those single atrs. I tried it by my own to copy the disks into a 16mB, but wether with SDX nor MyDos I could see any files. Itś an unknown file format.

Roydea6 Posted January 18, 2015 Share Posted January 18, 2015 (edited) These are Boot disks with no file system files and no VTOC. And are PAL only.. I just don't know if they need to go into all (8 ) of the drive slots or it you need to swap them at some point..

Stefan Both Posted January 18, 2015 Share Posted January 18, 2015 ... or it you need to swap them at some point.. That is the reason. You have to swap it, and hit start key. No chance for an unwatched start. And Pal is no problem Stefan Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted January 18, 2015 Share Posted January 18, 2015 (edited) Yes, but converting eight 130k bootdisks into a single file will take some time and work. You may ask Fandal if he is willing to spend this time... Guess no-one else is doing this for you. (Besides, I do have similar raytracing animations that work with less RAM and/or are available as file-versions.)

Stefan Both Posted January 18, 2015 Share Posted January 18, 2015 I see. I thought, it is a single file on each disk, that I have to copy into a folder to make it running. That is, why I asked if someone is able to copy it into a larger atr. If it is more complicated, I reject my question. Stefan Quote Link to comment Share on other sites More sharing options...
Caterpiggle Posted January 18, 2015 Share Posted January 18, 2015 Hello Fandel, Your link has come up with error 404. The file does not exist there ... please re-direct me to somewhere else to get that demo of 1 Mb Quote Link to comment Share on other sites More sharing options...

Evil as I am, I asked Fandal about it and he told me that "It would take a lot of time and work for sure. I'm NOT going to do this. :)" Quote Link to comment Share on other sites More sharing options...
miker Posted January 19, 2015 Share Posted January 19, 2015 Well, you can always try to contact Homesoft, as he does such things with games, so maybe he can do an exception. Quote Link to comment Share on other sites More sharing options...
