Well, I guess next question is very fool... but really I cant understand how to do. I started the RMT routine and use a VBI routine to call : jsr $3400+3 // Play RMT but when the game ends I use the next sentence: jsr $3400+9" // Silence RMT But the music still go on. I think because VBI still working and re-start the music. Once you had created a personal VBI, you can disable?

Thanks for thinking.... But I discover the fail.... RMT routine use some bytes from page zero and have conflict with some of my routines. Works fine now! After all, will be good to know what are the limits of the RMT routine... or could be applied in any game if free memory exist?

I use the RMT routine in a game. I know RMT spend a lot of CPU speed but I no have idea what are the conditions to get no failed working. When I use for the game presentation is OK, works fine. But when i try to call the routine inside the game (as background music), the sound crisp and sound very cutted. I dont know what are the factors to consider to free speed cpu for using RMT routine. My game use fine vertical scroll (everu DLI line Gr.12 has VSCROL). I put the RMT routine as VBI deferred (20000 cycles). Eve if I call directly inside the main loop, the music sound cutted and crispped. Maybe I think the fine scrolling with VSCROL spend much CPU. Any other idea to fix this problem?

Not exactly, there are less than a thousand unique games on the 2600 and something like eight times more on the A8. It would be fun but does the A8 really need this? -- Atari Frog http://www.atarimania.com The 2600 have simple but funny stuff that dont exist in XL/XE. Good games as Adventure, Combat, Air sea Battle, Haunted house, E.T. (cough! cough! just kidding!)... Maybe for the 64 XL/XE users dont sound cool, but 16K users (even 5200 users) could see enhanced your machines.

Well im not thinking in get a directly cartridge port for XL/XE. Emulate the 2600 cost great CPU speed if the XL/XE try to emulate as interpreter. Maybe the best idea is to design a PC software that converts .BIN 2600 to .XEX file. The translate happens as a aditional step, as compiling. to Wrathchild: Sprites multiplexers in 2600? you design one sprite and can repeat 2 o 3 times? ... mmm... I'll try to read more about 2600 technical information. But your Combat games looks exactly like 2600 version. Well, the good point is if a 2600 emulator exists then the catalog XL/XE games increase at least 2 times! ... and think in the old 400/600XL models.

Is factible to design a 2600 software emulator in XL/XE series that could use all the existing ROMs ? Strong points: - Similar cpu microprocesor 6502 vs 6507 (1.67Mhz vs 1.19Mhz) - XL/XE series have more RAM (64Kb) vs RAM/ROM (128b/4K) from 2600 - 2600 Graphic screen is 160x102 will be covered with extended lines in XL/XE GR.7 - I think chip sound is the same with less channels - 2 standard joysticks in the same way - Same amount of colors - More sprites and similar engine in XL/XE Cons: - System graphic video mananging is different. Maybe this is the great effort to do in the posible emulator. But, i dont know the technical hardware in 2600. Maybe there are more differences to say.

When this type of things happens.... Id prefer to go to sleep and wake up next day with a great cup of coffee.

And finally, for the Action! popularity is necesary to get the manual. Im sure many people have the original manual, but there is not a electronic copy in the web. The links added in this post are very interesting, but only the manual could revealed the complete posibilities.

We all Know Action! is a great language for Atari 8bit. But, everything has cons, and I never heard something negative with Action. What could be the cons about this language? i.e. could create projects using aditional 130XE memory? Maybe, im wrong, but never I've seen a rich, arcade and complex game written with Action! , What are the best commercial examples? I only remember games like ROTO.

Again a little problem, but i cant find the solution. I use this sentence to clear the player0 memset(pyb0,0x00,255); Then I noticed the player0 appears with garbage, but when i set: memset(pyb0,0x00,256); The garbage clears all... in this way the command works. I wrote the sintax form memset: void* __fastcall__ memset (void* p, int val, size_t count); What means type "size_t", is a char? integer? Ive noticed sometimes the command memset works, sometimes not. What could be the problem?

Incredible!!! ... you do exactly in the center. That WAS the problem.... thanks a lot!!!! I dont know why i added the poke(53768,0); poke(53775,0); Maybe i read in Atari mapping for initializing sound, but i forgot to test in the real hardware (emulator continues sound). I've remark the line and the program works cool again. Thanks again!

Well, Another problem... Im tired to fight every day with this, but i'll go on... I defined the sound with this formula: It appears to be fine and i heard cool in the emulator. But the same program only makes low level "brrrp" sounds instead. I use sound in 3 voices. My question is... .....exist sound bios routines that accidentally I could changed? ....is there any conflict in the mapping memory with the sound? (i.e. RTCLOCK) i'll appreciatte your help, thanks.

Um, ok. Actually the C-64 version may look better in some ways but I really want an example of how the c64 version is more like the arcade than the Atari 8-bit version. Only complaints I have of the Atari 8-bit version is that is does not say Wonderful after every 10 screens, it is probably a little harder to stop and throw the ball behind you than the arcade, They chose to use artifacted colors at the top and bottom for seom reason, and the copy protection used to make the drive a little noisy and when I upgraded to us doubler it only loaded half the time because the copy protection would cause a reboot. Well, is not 100% exact as the arcade, but the Mr. Do! version of C64 in my opinion is better than the atari version. The game that really brings the atari is Frogger programmed by John Harris. Are you kidding? Mr.Do! Atari version has some details more near to arcade machine. Look the intro and win life animation screens. Ms.Pacman C64 version is crappy (I guess still the C64 launch). Atari version have better smooth movement and better level colors. Even when both version use the same amount of colors, the level color from a 128 pallette looks more realistic.

Thanks, like I suspected, only GTIA modes can supprot 256 colors. It's interesting GPRIOR controls this effect in text mode too. Thanks again.

There is a way to get control above all 256 colors from Atari pallette. But, practically exists only a pallette of 128 colors. What could I do to work with 256 pallette? What the technical difference?

I've never used the fifth player before. I always thinked there is a magical mistery about this bit that join all missile into one player. BAAAHH !! Now, I know it's a disaventage, because we lose one color in screen. It's better to work as missiles and ignore the GRIOR 4th bit. Really, the Atari sprite machine could be new and excelent in 1979, but in 1984 was very old and limited. But, games like SWAT make me think there are ways to manage very well with apropiates routines. Thanks for the help, i can finally get my fifth player! Mario

Hi, How can be set the fifth sprite? The Memory map say use GPRIOR with 17 (1 prior and 16 mix missiles into one player). What address are used to move horizontally, change wide size or set color? Regards Mario

There is not Justice in that contest... people choices only uglys games... I suspect anyone download the atari emulator for testing only one game. However, thanks for keep the Atarian presence. Allas

I have a 130XE and in his back exists a hole. With a screwdriver you set the ink/tint color, from B/W until colorfull screen. Maybe the 800 has the same hole, isnt it? Mario

Very strange, AtariWinPlus emulator accept ATR (disk images) and XEX (Atari executable files) . But, there is another web site with ATR image with O'Riley's mines O'Riley's mines just only use the diskette 14. Mario

... ..... O'Riley's Mine ????.... O'Riley's Mine

Maybe a good idea is to create a DVD production ... easy, cheap and more accesible. Forth in English easy to learn.

I surrender nothing strange happens, maybe the NTSC system is different.

The screen go blank, nothing more happens....

Speccy has the better technical innovation software, they developed the isometric adventure games, software sprites, realistic mathematical events.
