Quite right, so that you could take snapshots of game screens etc .. on the fly (like photographs) 900162[/snapback] Yes, the wire causes a monitor change interupt so the Multiface cart could stop the running program and break in. Unfortunately it is a no brainer to disable that interupt and most games disabled it so that was quite useless in practice. But I liked the file manager/copier of cart. Another cartridge product is the ROM-drive from a german company called Dela. This was a 512KB bankswitched rom cartridge. Using the accompanied software your favourite programs could be put on EPROMS and the ST saw the ROM-drive as a read-only harddisk. Robert

Yes, I bought it on tape here in The Netherlands when I was a child. Later I converted the tape version to disk (not an .exe but a bootdisk with the original tape loader screen. I just replaced the tape loading code with disk sector loading code.) I've attached it to this message. Oh, yes, it runs on a standard 64K machine. Robert P.S. When I tried to attach the .atr file I got an error saying: "Upload failed. You are not permitted to upload a file with that file extension.". Since when is that? Tried it as a .zip file now. bbsb.zip

For graphics/music you could use the Ultimate Ripper Cartridge. An alternative would be An Cool's Explorer Cartridge. If you like to disassemble code, I used the Bugaboo debugger, part of Turbo Assembler. Since it used its own screen drawing routines, it didn't interfere much with the running program. Great to hack ulilited lives etc. Robert

Here a small report of the Dutch Atari Day. While driving to Dordrecht it was snowing. This caused the road to be slippery but we arrived safely. The event was held in the sport hall of a school. Unfortunately this was probably the last time we can use this location. It won’t be allowed anymore to use the school for “private” purposes. It was not as busy as last year but still more than enough to make the day a success. A few people were selling games for Atari 8bit, 2600, Lynx and Jaguar. Myself picked up some difficult to get 8bit games from Eastern Europe. It seems that the 8bit users are most active here. Symen (Mr. Atari) showed his MyIDE interface for the 8bit. This makes it possible to play digitized movies on an Atari 8bit. Very impressive. Guus demonstrated a prototype of an improved version of the Turbo Freezer for the 8bit. This makes it possible to freeze every game and then saving the state to (ram)disk and disassembling and changing the memory contents to poke unlimited lives for example. Saved states can at a later stage be loaded, continuing the game where you left. On board there is room for, I believe, a 512KB ram chip and a 512KB rom disk. The device can also emulate (bankswitched) cartridges. Also Guus had brought his tools to help people upgrade their Atari ST memory and help with repairs. Also shown was an Atari Panther prototype development system. Unfortunately the owner does not have any software for it, so there was not much to see. If somebody knows where to find software for it. Let me know. I showed my 7800 with CuttleCart 2, a 7800 cart where you could load and play almost every 2600/7800 from MMCart. At least two people were considering buying one too after my demonstration. Luckily Chad is preparing a second production run now. Another guy had brought a bunch of 7800 computers to sell. He gave me a broken one (no picture) for spare parts. When I got home it turned out that it was easily fixed so I now have another spare 7800. Thanks. And finally there were a few Jaguars to play networked games. Pictures of the event can be found at: http://www.mr-atari.com/dordrecht2005fotos.htm[/url] Concluding, it was again a great event and I’m looking forward to next year. Robert

Maybe it is because there is no PAL version of Robotron Robert

I was thinking of this aswell. I've been looking in de Microsoft developer documention for functions to directly access sectors on the harddisk but I couldn't find something. But an article on SysInternals has some pointers to the native API were I believe this kind of functionality lives. There must be some documentation in the "Device Driver Development Kit" (DDK) and Windows NT Installable File System Kit (IFS Kit) which is only available after signing a NDA. See also the Book list. Robert

The original Knucklebusters tune is great. Very strange sounding. Not everbodies cup of tea but I liked it. Do I understand it correctly that Rob Hubbard did an experimental version for the YM? I never knew that. I found the Cuddly Demos version of Knucklebusters quite nice, but that is using samples instead of YM sound. For a great Knucklebusters remix try the Sidology CD from Marcel Donne. 18 minutes of Knucklebuster heaven Robert

Try YM-Rockers for some "modern" ym-sound. Especially TAO has perfected YM-Sound with multiple SID sound channels. Robert[/url]

Hi Analmux, The day last till about 17:00-17:30 I believe. I hope to see you there. Robert

TEX had certainly a great influence on fancy hardware tricks but they were not the "discoverers" of overscan & sync-scroll. A guy named "Alyssa", discovered the lower border technique. Why the hell he had the idea to switch refresh frequencies at the last scanline is beyond me, but this idea is the bases for all border and sync-scrolling techniques. TEX picked up the idea and applied it in the BIG demo and NeoSlideShow. Soon the upper border was opened, which required more effort to sync correctly and I believe TEX was to first to open the right border aswell (Amiga Demo). The first all-border fullscreen was by the TNT-crew (Union Demo). Sync-scroll, which used the border opening techniques, is invented by TCB, but I believe another swedish demo crew (Omega?) had the same idea at the same time. It was first applied in the Cuddly demos. Full overscan is a bitch to code since your border opening code has to be synchronised with the electron beam, and your "other" code has to be interleaved with that. So count those clockcycles and discover the errors in Motorola's timing sheets. More information: Atari Demo History Opening the borders Robert

Huh, it actually works better than advertised Not advertised but also working: - Fractalus prototype bankswitching - 3F 512K bankswitching - Pokey + HSC support Robert

Hi Lars & others, I've done some more testing. First I dug out my spare Jaguar + CD and did the same test as in my earlier post. It did have the same results. JagMind worked in 60Hz but not with 50Hz and retail OS. But it worked in 50Hz with other OSes. Both Jaguars were K-series. Next I burned a flash-rom with the M-OS I posted earlier. It had the same results as my retail OS. Thus JagMind was not working at 50Hz. Then I burned a flash-rom with the K-OS. Now JagMind worked in 50Hz. This sugests that my K-series Jaguar OS is not the same as the K-OS I posted. Also Serblander wrote that JagMind also didn't work on a M-series 50Hz Jaguar. This leads me to the conclusion that you can't see on the series letter what version OS you have. It may be either one. I should dump my retail OS to see if it is indentical to M-serie OS I posted. So my conclusion is that JagMind has problems running on PAL Jaguars that have the M-OS I posted. But is runs correctly on PAL Jaguars with all other OSes I tried and on all NTSC Jaguars. Robert

Hi Dutch Atari Fans, On sunday 13 februari 2005 there will be an Atari day in Dordrecht in The Netherlands. Everbody is welkom, even non Dutch. It will be a general Atari meeting with Atari 8bit, Atari ST and game machines like 2600, 7800, Lynx and Jaguar. For more information, read the messgages on Yahoo groups (Dutch language): - atari-nederland - atari-nl The location of the Atari day will be: Stedelijk Dalton lokatie Titus Kapteynweg 3 3318 EC Dordrecht. The entrance for the Atari day is at the backside of the building. Possibly it will be marked with a blue Atari flag. The main entrance of the building is closed. See you there, Robert

Hi Lars, It appears the the M series Jaguar had a different ROM than the K series. I don't know what the differences are but using WinDiff or WinHex compare function, the difference is more than just a few bytes. Attached the two ROM dumps I have. When I have time this weekend, I will try them in my Jaguar. Robert jaguarbootroms.zip

Hi Lars, I did some testing on my copy of Ocean Depths because I had some troubles getting to work it as well. JagMind loads and displays the title screen, but starting the game hangs the Jaguar. And I don't think it is a CD-R problem for me because I can make JagMind to work. I have a modulator less Jaguar with 50/60 Hz switch and 5 different OSes. Here my findings with JagMind: - Works if I put the console in 60Hz with all OSes including the retail OS. - Does not work with retail OS and 50Hz. - Works with Dev94 OS and 50Hz. - Works with BJL and 50Hz - Works with JagOS and 50Hz. So the culprit seems the combination 50Hz and retail OS. I tried booting the CD on retail OS/50Hz with Protector SE and BattleSphere Gold but that doesn't help. Could be. I know of one Jaguar that plays all games except the cartridge version of Iron Soldier II. But it does work with the CD version. As far as I know there are two versions of the retail OS. Maybe JagMind has only troubles with one of them which would explain that not everone has problems running JagMind. Hopefully this information is useful to you in determining the cause of this. Robert

I downloaded the file from the location you gave above and made two perfect working CDs of it. So it works for me No, those are the files from the signing process. The hashtab.cd file is already padded to 1025 bytes and stored as track05.raw. Thus the files in that directory are not needed to burn the CD correctly. Robert

The morphing in Cybermorph does not stand for the intro annimation but the change of shape in the ship you are flying. If you go forwar or backwar you see the ship change. And this effect is just done by interpolating the vectors of the object between the start-position and the end-position and it not very time intensive. Robert

The hi-score cart rom is a seperate file in the STARTUP directory and not included in the CC bootrom. The HSC.ROM file in the STARTUP directory is the same as the rom dump I have of the Hi-score card. Robert

Another problem would be how do I know that the solution I've come up with, is already patented. I don't have the time to browse the descriptions in the patent database to see if something looks like my (in my opinion trivial) solutions. So in practice, you wil probably write something and hope that nobody will think that you are doing something that is patented. Robert

Floppy data transfer is a raw serial stream. Thus including marker bytes, gap bytes, and CRC bytes. Yes, I think that would be the way to go. But the board could also be pluged in the external floppy port. A switch could be made inside the ST to swap the internal and external drives. The board should contain all the logic to emulate a floppy and use USB for example to retrieve the data from a PC. Not an easy solution. Robert

You can use use almost every port for datatransfer. I believe ghostlink supports serial but PARCP supports parallel connections to a PC. The problem with these kind of solutions is that it needs additional software on the ST. And most games/demos don't like that. Besides these programs allows you to access files on the PC harddisk but do not support disk images. And since a lot of games/demos use boot disk (e.g. disks without a file system (no FAT)) they will not work. Thus these solutions are mainly used to transfer files between ST/PC and not directly run programs stored on a PC harddisk. To load & run ST games/demos from a PC you need a solution that does not need additional software on the ST. Thus you need some hardware/PC software that connects to the floppy connector of a ST.
