  1. It doesn't matter which chip you socket first: it'll be the other one.
  2. The missiles either share the colour of the corresponding player (0-3), or - if combined as a fifth player - they share a fifth colour. Remember there are only nine colour registers in total; four missile/player colours, four playfield colours, and the background colour. The fifth player takes the colour of playfield three.
  3. If he's a bulk reseller, it's strange that in the video on the SIO2PC page he is unable to even pronounce the OEM's name. All the product descriptions appear to be direct cut-and-paste jobs from Lotharek's site. Hopefully he is not selling U1MB and SIDE2 with anything but the original (Candle) firmware on them. If anyone knows otherwise, I would be interested to hear about it.
  4. Interesting. That is Lotharek's product.
  5. Dunno about a cord. Lotharek's SIO2PC USB is a safe option and connects using a USB type-B connector
  6. Bogus FTDI chips may refuse to handle divisor 0 transfers. Legit is preferable.
  7. Mode 11 intrinsically presents all sixteen colours at the luminance dictated by bits 0-3 of the background colour register. Mode 10 would probably be the most useful of the 'GTIA special' modes were it not for the shortage of colour registers, which results in nine usable colours (without mid-line register changes, etc) instead of sixteen. Lastly, mode 9 allows all sixteen luminance values in a single colour hue. A series of compromises: one can either have all the colours (mode 11) or all the luminances (mode 9), or just over half the ideal number of freely selectable colours (mode 10). One might complain about the C64's fixed colour palette, but it wasn't the only machine to make compromises. Sadly they didn't implement a bitplane version of mode 7 with - at the very least - nine freely selectable colours (using 2 bits on the first scan line plus 2 bits on the second) instead of four. Among things that were 'new' to me during recent years are mode 15 PAL blending, and the pleasing hi-res tritone effects possible with player/missile graphics underlays (U1MB BIOS setup menu being one example).
  8. LOL. I meant MADS. MA65 is the Macro Assembler I wrote in the 1990s. Perhaps I have a subconscious bias too. I appreciate there's more than one way to shell a nut. MADS has its own linking facilities as well (I wrote a symbolic linking loader for the WIP GOS which uses MADS' relocatable binaries as executables), but I never played with them.
  9. Yep: I read your clarification. But just taking the bull by the horns and figuring out how to organise one's code under the OS in MA65 is preferable, IMHO, for someone already heavily invested in MADS than delegating the job to a CC65 linker profile and obfuscating a lot of the complexity. This is my generalised opinion on the matter and I wasn't attempting to directly gainsay your suggestion, however. I don't want a quarrel about it either.
  10. Any suggestion of turning to a higher level language.
  11. This is all much, much easier in assembly language if you're already adept in 6502, IMHO.
