In multiplexing, you need to select one of the four groups first, before reading them because the same bits represent different values, this is what screws the emulators ;) 1) Write a value to address 0xFF9202. This sets the control lines on the multiplexers. 2) Read the values at 0xFF9200 and/or 0x...

Just to let people know, if you're installing VS2015 for this purpose, the C++ Language is NOT installed by default. When you run setup, you need to select it as a language in order to use this tutorial. (You can also use "Modify" if you have got VS installed already). This was a major step that I m...

Technically the music is a straight up, 8-bit sample at 12.5 khz .. that damn looping tho, i know someone who might be able to fix that if I can convince him its worthwhile

And some rather nifty TEXT displaying TEST program written by XiA ;) Im sure he wont mind me spreading this, but whether he owns upto it or not is another matter :P NUMBER_OF_VBLS_BETWEEN_UPDATES equ 5 JAGPAD_SELECT_GROUP_1 equ $fff7 JAGPAD_SELECT_GROUP_2 equ $fffb JAGPAD_SELECT_GROUP_3 equ $fffd JA...

And here is the famed Jag Code.. straight out of Frogger... I've included the actual bit representations too for your convenience... sorry for the lack of comments tho :P ;****************************************************************************** ; ; Jaguar PowerPad Code ; ;*********************...

I've some code for the Jagpads, word of warning though... its not at all reliable on any emu i've tested, its either one button or screws with the keyboard or some other brand of wickedness... bear with

On the subject, it COULD run on the falcon, everything is there really too ... only I might get someone else to do the fixing

It is STE only, thats down to the use of Hardware scrolling .. But, by using the STE and making the game for it, I get to use all the other kool STE bits like the DAC and the jagpad :P The music is done using the DAC ;) Jagpad code is horrendous on ANY emulator, it just doesnt seem to be top priorit...

Did he use STOS for programing? No, I switched to ASM for this one, STOS was just a bit too slow for frames when everything was running full tilt ;) Handling the second level is going to be a challenge for sure! Will it be parallax? No Idea, As im only currently on Level 1 ... a playable demo is in...

Thanks for the comments guys, the arcade version has more height .. i mean in retrospect it COULD have been done with overscan but then more sprites would be needed and it would slow the whole thing down. though I think your version has a wider screen. Yeah the original is tall and thin for want of ...

Frogger has been unleashed to the world.. get your copy here... http://www.atarimania.com/game-atari-st-frogger_30782.html I would like to take this opportunity to thank all those people that have helped me over the last 6 months... You know who you are ;) Sys Reqs ---------- 1Mb STF/E TT030 / Falco...

Wouldnt be right for me NOT to plug my own game

http://www.atarimania.com/game-atari-st ... 30693.html

Only uses the directions and A on this version atm...

Only problem I see is the cables I have the connectors cannot be dissasembled, Mine was similar to this... turns out, although at quick glance they couldnt be disassembled, they could be prized open.. mine were merely glued together. Bought from "Retro Computer Shack" on Ebay... If it LOOKS similar...

I bought an Atari 520 STm with a 1MB upgrade yesterday Congrats on this :) No encouragement from me regarding an STE lol One thing tho... There has been a lot of debate about HOW to upgrade the STM to 1mb safely... there are "piggybacked" RAM solutions and I wondered if this is the solution that ha...

Can I point you to this topic http://www.atari-forum.com/viewtopic.php?t=28665 I had a lot of issues with this myself... and this seems to be the best answer tbh Add 150 ohm resistors on R,G,B signals. DO NOT add resistors on V-sync (blanking signal). Boucing screen solution - add 100uf / 10v (or 16...

It refuses to run on TT or Falcon (Hatari emulation). Could those checks be post-poned until final version, so that people can test whether / how well the game works on them? Not really, its not going to work on either machine... so rather than let people look at a black screen and/or crashing thei...

did you use any of the arcade code, or is it a complete new version? No, no.. Its a complete "new" version as it were... Wrote it in Assembly. It actually started as a learning exercise for learning ASM and turned into the game. I already had the sprites from the STOS version and needed to learn ho...

Thanks!

Okies... Version BETA 3 .. Sucks that the Keyboard and Joystick system worked on ACCIDENT! Mega thanks to Steve @ AtariCrypt for his MegaSTE testing that revealed this!! major Ef up on my part!! :| So... fixed (Again! - and hopefully for the last time) the keyboard and joystick controls. lol... so h...

Zerkman should be added to the credits

I stand corrected!!

Thanks for pointing that out DMA .. Perhaps I should read my mail more thoroughly next time

who i should i credit for the sound fx? - That would be DMA-Sc, His work is really good, just waiting on updated sfx and music file to complete the set. There are too many STe/TT/Falcon master-racers as it is and the older hardware often gets forgotten. This has always been precisely my point lol. ...

Sadly this leaves me with no way of actually testing the code I've some source code I could send you if you like? Its quite nasty but DOES give you variables like joy_up (0/1) to work with... if you wanted a copy, I could tidy it up, comment it a bit and send it to you? I DO own a JagPad so I know ...

Updated version, almost complete.. SYS REQS -------- ATARI STFM/STE (TOS 2.06 Compat) 1Mb of Memory or more Colour Television/Monitor N.B This version is NOT Falcon/TT/HADES compatible, its unlikely the actual game will be either. The game was always developed for the STFM/E range and this has staye...

All SC1224's I've used has been like this.

Aah thats a shame, for the price of a SC1224, it seems like a nice collectors model but not really useful for my needs tbh.

I DO thank you for your input tho guys, guess its a standard 14" CRT !! .. at least I can pick this up for £5 UKP or even less

What needs fixing for TT? Well, It RUNS on the TT, in ST-Low 'mode' but there are three major issues that need addressing really... 1)The screen is pure black all the time (If you press space to start a game the music plays, you can die and return to GEM, BUT all the while the screen is entirely bl...
