  1. If money is an issue, because I see here people worrying that ROM purchases would kill carts, just make the ROM cost the same as the physical counterpart, that way the option exists. As long as my living space doesn't get cluttered with things I don't want, I'm down with paying a pretty sizable amount, I just want the option.
  2. Hey there, friends, I wanted to ask something: Where can I find here a list of games and/or homebrews that detail what type of expansion chips or additional cart hardware do they use? I want to see things like, at least on the homebrew side, which games use additional hardware like, like the Activision DPC, or what other additional hardware exists now that is being used, now that we have so much technology at our fingertips.
  3. I can't wait for it, personally. I do not like having a massive physical collection for something that can take less than a 100 MB on my Google Drive. Plus, having a ROM version of a game futureproofs it. If not for ROMs, I feel like a lot of these cool homebrews may not be playable in the future, when they're not being produced.
  4. Yup, I do, and it runs on the emulator! Woohoo! Thanks guys!
  5. Okay, so I took the advice and located the macro.h and vcs.h files into the same directory as demo.asm. I also united the -l and -o switches to their directed file/filename. It's still not working however in PowerShell though. Anything else that I need to fix?

  6. So, thing was that I didn't know whether I needed to set a path in my computer to the dasm.exe executable. Apparently, as long as I'm in the folder when calling it, or I'm entering the the folder it's in through ..\..\dasm_assembler\dasm-2.20.14-win-x64\dasm.exe , it seems to work. Question now though, is that I don't know if I'm writing the command correctly: PS C:\Users\pablo\Google Drive\ATARI_2600\dasm_assembler\dasm-2.20.14-win-x64> .\dasm.exe kernel.asm -l kernel.txt -f3 -v5 -o kernel.bin -o Switch requires file name. PS C:\Users\pablo\Google Drive\ATARI_2600\dasm_assembler\dasm-2.20.14-win-x64> .\dasm.exe kernel.asm -l kernel.txt -f3 -v5 -okernel.bin -o Switch requires file name.

As for what's in the folder I have my file in: PS C:\Users\pablo\Google Drive\ATARI_2600\projects> ls Directory: C:\Users\pablo\Google Drive\ATARI_2600\projects Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 3/10/2021 8:45 PM 1829 demo.asm And as for what's inside the file, it's not what's in Andrew's book. I took this code from 8bitworkshop IDE [vcs] - examples/vsync.a , as I just currently want to get something assembling before anything else. I've always have had problems with command line assemblers and compilers. They seem really hard to understand and use. The code in that link is: processor 6502 include "vcs.h" include "macro.h" org $f000 ; Now we're going to drive the TV signal properly. ; Assuming NTSC standards, we need the following: ; - 3 scanlines of VSYNC ; - 37 blank lines ; - 192 visible scanlines ; - 30 blank lines ; We'll use the VSYNC register to generate the VSYNC signal, ; and the VBLANK register to force a blank screen above ; and below the visible frame (it'll look letterboxed on ; the emulator, but not on a real TV) ; Let's define a variable to hold the starting color ; at memory address $81 BGColor equ $81 ; The CLEAN_START macro zeroes RAM and registers Start CLEAN_START NextFrame ; Enable VBLANK (disable output) lda #2 sta VBLANK ; At the beginning of the frame we set the VSYNC bit... lda #2 sta VSYNC ; And hold it on for 3 scanlines... sta WSYNC sta WSYNC sta WSYNC ; Now we turn VSYNC off. lda #0 sta VSYNC ; Now we need 37 lines of VBLANK... ldx #37 LVBlank sta WSYNC ; accessing WSYNC stops the CPU until next scanline dex ; decrement X bne LVBlank ; loop until X == 0 ; Re-enable output (disable VBLANK) lda #0 sta VBLANK ; 192 scanlines are visible ; We'll draw some rainbows ldx #192 lda BGColor ; load the background color out of RAM ScanLoop adc #1 ; add 1 to the current background color in A sta COLUBK ; set the background color sta WSYNC ; WSYNC doesn't care what value is stored dex bne ScanLoop ; Enable VBLANK again lda #2 sta VBLANK ; 30 lines of overscan to complete the frame ldx #30 LVOver sta WSYNC dex bne LVOver ; The next frame will start with current color value - 1 ; to get a downwards scrolling effect dec BGColor ; Go back and do another frame jmp NextFrame org $fffc .word Start .word Start Let me know if you need anything else, please. Really just want to assemble something so I know I am able to actually program and try things out.
  7. Hey, guys, I'm trying to follow the instructions on Andrew Davie's "Atari 2600 Programming for Newbies", in chapter 9 where he starts teaching how to use DASM. Thing is, I'm having troubles trying to get it to work. Can anyone please help?
  8. So, is this a program for the A800, or is this like a replacement ROM (as in OS) for it? I'm kind of confused.
  9. I hope this is still being worked on. I played the latest version and it's really cool!
  10. The link for the NTSC version isn't working anymore. What difference is there between the NTSC version and the PAL version?
  11. An FPGA can be as cheap as $10 - $20. What are you talking about, my friend? Besides, FPGA is the future of retrogaming, haven't you heard?
  12. That sounds like a wonderful idea and something that I'd like to participate in
  13. So I'm very new to this community, and I can't really find much information concerning this, so here goes: When will Gradius be available to buy again? Also, will it every be possible to buy the Rom (or pack of roms) the same way that CollectorVision does? Again, just a question, not trying to enrage anyone here. From what I've been able to see, roms are a no no here, but I can't really find out why. Thank you for your patience.
  14. I forgot to thank you guys for your help! Thanks @Serguei2 , thanks @Mike Harris !
