Over the top? Never! It should be mandatory for all Atari owners.😀

Yeah true, but I can't help wondering how people come to these valuations.

@jonesypeter Hi, I've attached source code for the first screen that you can compile with MADS. You could experiment with colors by altering the color table, and also where the dli's are happening by changing the display list. You should get a better handle on how DLI's and Colors work. Even better if you are able to trace through it with the Altirra debugger. Hopefully this helps you out a bit. GraphicModes.xex GraphicModes.asm

I like TBA and have ordered several things from them, but even with international shipping it's usually cheaper just to buy directly from Lotharek. Covid was the exception. For example with shipping included, U1MB is about $120 from TBA or ~$111 directly from Lotharek

Just in case anyone wants to give it a try, attached are the 64 col, and 80 col versions. BZ64.atr BZ80.atr

It's good enough and looks a ton better than the Apple2 style. Maybe, I haven't had time to give a real try. But it's Beyond Zork for the A8 which I never thought would happen, so I'm already very happy.

Thank you @jindroush This is excellent! I was able to compile Beyond Zork with the ST style graphics instead of the Apple2 style, for both 80 and 64 column.

If you want to use the Goex or Gotek externally you have a few of choices for the adapter cable: https://www.ebay.com/itm/334756348147?hash=item4df10880f3:g:WakAAOSwDIdj804R&amdata=enc%3AAQAIAAAA0E%2FNQQLq17xw3AVHmlQ2vZ9XZTyN5hzZ4Ju42KSpU8D8M%2Fj%2F%2FiEpMum0ywDhGstKKjTmD2tmhijgsUEGnONAc5BE6WXAtWTP6hlLCGhl0sFoXnDrz2FkZVOhejxooRUfSOsAv%2BrSuHPMnEGkkV6AAShxVrg4d0b5FDGZudJrwz5VmHazDhhMqwl81HTLu8FgyQZousfpVEH5cCKf%2Fwdj9bXREb5TzseP9j%2BVJC9l8mfUNe85cPM4XPs%2B%2F2t7frFXLGdf495KfD18QtkzEIuQv1s%3D|tkp%3ABk9SR7jAuZ-xYg https://www.ebay.com/itm/334841786603?hash=item4df62030eb:g:JvwAAOSwpNlkQkuW&amdata=enc%3AAQAIAAAA0OvZBXYqz3J38cbvAsoQwSgS4ozJNAmO7XOjCsqjdZl1OkTQD%2FhLJzrc4XJwdC5tFW3LBBlIBKcefyKHLtBcXjpCNL3lGlwyLlEspYgH8teWbva%2Fdbon9IykMdhmsYfLz3StEqMzOhgfhRhttPzgoiWspluUhExsfyLUHE3HQx2Nl1GFag1ojDPjEIZbLEpJHeh30sbNFA5NbOKLxwNCL0STZwx4RcZ6uSUu2Y0sqVY8dWJZzW9kEIzFcaDcG1tUjT17GMvol%2B588fiamPuB0tU%3D|tkp%3ABk9SR7jAuZ-xYg https://www.ebay.com/itm/114409935581?hash=item1aa35d12dd:g:oSQAAOSwInxfNphw&amdata=enc%3AAQAIAAAA4PDYRN116Aaq00Biim3ZF1xtyA4bkguLBEIOHq%2FXwQrZCXDR87KXOw1KJ%2BBSdKuQ8rB2s%2BUvwipDClz2GfIZfzotDI%2FQlPX%2FDVNX8eiUevoWVEpOwHjJbEpe%2FkYZM96WHh%2Fx8J8m3TlThxtu%2Bj4dt5dd%2FA4SH1INIWx7Z4d0Jf0Ncx4Sy8B1CuRxrP%2F8TZndlBGLSu1Y67%2FchO8YPJI%2F7t%2BxWEbV1lnR7lVnS97J14VZzZqufBlCpf0zaZPv6jy1tbNdWEVEA32U3hHSfxoo%2Be%2F3544WAqOxewb6Qj%2FfH5KF|tkp%3ABFBMvsC5n7Fi Then you just need an external +5V power supply, I can't remember exactly, but I think 1-2 amps should be enough. I've made both the floppy cable and power supply before, but I don't recommend making the floppy cable since it is a little complex and there are other options available. Here is an older thread with more details: Edit: It looks like the first vendor sells it with a usb power supply cable as well so you can just plug it in to a phone charger and you're good to go.

IMO start with the 400/800 Hardware Manual to get a feel for the hardware. Next read the OS Manual and get a feel for how the OS works. Get a copy of 'Mapping the Atari - Revised edition' PDF or hardcopy, this will help a lot when you want answers to specific ROM/RAM locations questions. Next try some different cross compatible assemblers MADS, ATASM, DASM, KICKASM, XASM, etc.(I prefer MADS) Then pick a development environment such as Visual Studio Code or Eclipse. I wouldn't recommend real hardware for development, it's slower and much harder to debug, you'll save a lot of time cross compiling and using Altirra(or another emulator like Atari800Win) to debug. I use Visual Studio IDE at my day job, but I prefer using the WUDSN/Eclipse IDE setup for Atari assembly development. It is a one click setup with no extra thought involved and integrates nicely with many different assemblers and @JAC! is continually making improvements as well as support for MAD-Pascal. And as others have mentioned Peter has tutorials on his website both for setting up WUDSN and tutorials for assembly. Next just start coding - it is the best way to learn. Refer back to the Hardware manual, OS manual, and 'Mapping' when questions arise and ask questions in the forums as well. There are many people here with extensive knowledge of the hardware and are willing to help when you get stuck. Good luck and have fun!

Ha ha, true for the most part, however.... ChatGPT has passed the BAR examination, albeit with a C+ average. As well it has written quite a few PHD thesis'. It has also been writing research papers for high schoolers and undergraduates, which has been very upsetting for the respective teachers and professors. I'm no AI expert but from what I understand, the limits to the potential are 1) the amount of data available and 2) the feedback received from users - compounded by time(And of course the original algorithms used to program the AI). The technology is very young, but it will only get better with time and larger data sets. There is potential there, But it may be decades away.

I was fooling around and I asked ChatGPT to write me an algorithm in 6502 assembly for Atari to display characters on the screen. It returned something mostly correct but had an opcode I didn't recognize. I don't know if it was illegal, but it wasn't standard. I then told ChatGpt that particular opcode was incorrect(It does understand context for the same session). First it apologized and then it re-wrote the code closer to something I would expect. The point is, I think it is mixing and matching code with what it 'thinks' is the best version. Just like with the assembly and as others have guessed, it's trying to build a version from all the little bits of basic it can find and mashing them all together. @Atarick420 I would start over and ask the same question but make it as defined as you can(such as requiring it to be in Atari Standard Basic Version C). Then look at the code and ask follow up questions or place additional constraints and it can re-write the output based on that. And keep in mind it's still a very young technology and may not be able to write something like that for a few more years/decades.

It's always the last %5, the last little bit of polish put on a game that takes the longest. I'm sure @fantômas will get it done and it will be fantastic.

Very cool @Stephen I know you stated you weren't porting the game, but what a great start!

Chronologically BASIC on a Timex Sinclair. Keyboard was terrible and it had some weird lag when typing long lines of BASIC - The screen got slower and slower to update graphically. BASIC on a TI994/A BASIC on Atari 800/130XE ASM, C, and eventually C++ on 8086/Intel

Archon, The Eidolon, Boulderdash, Loderunner, Beach Head 1 and 2, FLight Sim 2(Even though it ran slow and was difficult to play.)Too many to list them all. Bruce Lee was my all time favorite. Sadly I never want to play that game again.

No need to update your profile, just go to ebay UK and search there. He does, this is where I purchased mine. Shipping is a little slow, but it works great.

You'll have to purchase an external floppy. However, unless you have a lot of old disks or access to a lot of old disks, I would recommend a Gotek drive. You'll need an external drive cable and power supply to get it working, which you can either make or buy. Here is a guy who sells both in the same auction. But they are expensive. https://www.ebay.com/itm/124259705395?hash=item1cee74a233:g:oSQAAOSwInxfNphw&amdata=enc%3AAQAHAAAA4Oi3SbLUILy2ho9UXSwi45EEnZZHJbPufxQM5sEFiIiw91%2FlFNBa1LL7ev%2BGVV7FLclTkfSF1MzuzKDstk4XhLIOpqOvqSZ3n01cGuozmbqleN%2BKATY%2B8HEwK%2BltQZ3y7ES7KtmeUlgfapwtF0SAvLTenZhkfcVqIVbXdqjSRFdsj6qZCNHpaajuNMf0EszcmlAJ2l6LXe%2BV8JA8CWSZEVKfs6Sv8rUCNpfhgvBWESCwKuhMY2uCWoUnHYgAmtT%2BBWIHz7UeQW0wxidYLDZAgEUIsJ3Mc2lZWixJp%2FTvcxz7|tkp%3ABk9SR_ak0-mEYQ I use an ST to Scart cable and then an upscaler like in thread: Since it is an HDMI out, it works for all modern day LCD's. I prefer this brand for a mouse adapter: https://www.ebay.com/itm/231881886751?hash=item35fd3ccc1f:g:Qf0AAOSwdj5h9jq8&amdata=enc%3AAQAHAAAAsEKimsrqaGjcVWJxjspAgygAQpgz9pT%2FeY48CpXfz1ymhb19fGseW017nptRZgIUntXJDAzDUm30vK0UfhNqe1BX%2BoyoMCnAmDJMkIfX%2FAFII693S9GqCF4aCaarPlRxG9Q%2BdRxaHJoC9bjoQ0A1JO4%2Fw8o%2BmF9Pb6jplZk4p4uPtNlG1WyzeuM9FYDzz%2Fldjkr93K%2FoFVUxGC6SbMNC7cpY7gFoeTfK5y%2Bez7EbZUu%2F|tkp%3ABk9SR7altemEYQ There are many solutions on eBay and other places for mouse adapters so choose which ever one make the most sense to you. There are definitely some cheaper alternatives. If you want a modern day mass storage solution, then I would highly recommend the Ultrasatan MINI from Lotharek. It needs some HD drivers - PM if you are interested so I can point you in the right direction. Good luck and welcome back to the world of ST.

It's well on it's way. It's almost exactly as I remember - keep up the good work.

It's a lot of fun!

Some bug fixes and a new sprite set by Tix. ROFTix.atrROF6.1ReleaseNotes.txtROF.atr

That shouldn't be happening with unlimited falls, but instead with SPR Collisions set to OFF. If you are playing with SPR Collisions OFF then there is really nothing to do but start over - Start Key, or F2 on Altirra.

I want one!

I would guess it may not work if loading from DOS, unless you can load as low as $1000 But the attached file should load from DOS @$2000 ROF.xex

Yes, this is because I am reusing the Yamo player 4 times as a mask, combined with PRIOR register value to give other hues. So technically you are falling on Yamo by doing that. The other possibility for extra colors is to change the registers on the fly like the example below: But you can see other problems with this method, not to mention it's a real timing nightmare: pha txa pha lda #$83 sta COLPF3 lda #$45 sta COLPF2 ldx #$0E ;Loops sta WSYNC nop nop sta WSYNC :4 nop loopColors :6 nop lda #$CA sta COLPF2 lda #$66 sta COLPF2 lda #$2C sta COLPF3 lda #$39 sta COLPF2 lda #$83 sta COLPF3 lda #$45 sta COLPF2 dex ;sta WSYNC ;:2 nop bne loopColors lda #$00 sta COLPF3 jmp SetNextDLI And the final problem with this method is the resulting vine/moving ladder: For this particular situation there just isn't a lot of options.
