  1. New dump surfaced: the Splicevision BIOS. Made by Victor Trucco in 2007, was since then forgotten somehow. placa1_bios.7z
  2. Folks at Datassette.org just released a ROM of Spy Hunter dumped from a Coleco Mania cart. It's another case of a game that couldn't be translated, just like Zaxxon. Spy Hunter (1985) (Atari Mania).col
  3. Inside the Spitfire cart. Very proto-ish, handmade solder points in the ROMs.
  4. Yes, just like Microdigital Onyx the Splicevision used a translated version of the Colecovision BIOS. Side-by-side, the Splice one is much more closer to the original than Microdigital's version.
  5. Now releasing the Jaxxon ROM. Unfortunately only the initial screen is translated. jaxxon (splice vision).col
  6. The game select screen is generated by the BIOS itself. Using the Microdigital Onyx BIOS everything appears in Portuguese.
  7. Hi everyone. I've just got the Spitfire (Looping) and Jaxxon (Zaxxon) carts in my collection few days ago and noticed that no one ever dumped any cart made by Splice. So, I sent them to Alexandre Casella, a repro expert, and now, almost 40 years after Splice released those carts, we dumped them successfully. In this post I'm releasing the Spitfire ROM. Jaxxon will follow shortly. Enjoy! spitfire (splice vision).col
  8. Hi pcrock, thanks for the reply. My european Atari Jr. got a UM6526P1 8850S chip. However, modifying it to NTSC will change the palette and make the console behave just like our brazilian Ataris, right? If that is true, it will defeat the whole purpose of using an european Atari. There is a handful of games that are only released in Europe or their 50 Hz counterparts are much more cheaper than the 60 Hz ones. That is the main reason I've got this console, to play european games. I don't get it, PAL-B and PAL-N are the same color TV system. The difference between them lies only in the color subcarrier frequency while using composite video. That is why TVs in South America often detect european PAL as PAL-N and, as a consequence of that, they fail to retrieve any color from the signal. It should be easy to convert a PAL-B console to the PAL-N system, but I still had no luck trying to do it. ☹️
  9. Hi folks, I am new at AtariAge. Months ago, I've got an AV-modded european Atari 2600 Jr. (Rev. F board) in a great condition for cheap. However, here at my country (Brazil), PAL-B compatible TV sets are rare to find. The closest color system that is supported by most TVs is PAL-N (PAL variation used in Argentina and a few more countries in South America). I tried to replace the 4.433618 MHz XTAL with a 3.582056 MHz one, but that gave me no colors in any PAL-N compatible set. Also tried to replace the 3.546894 MHz one with a second 3.582056 MHz XTAL, but still gave me nothing but B&W picture. Is there something I can do to make this console output PAL-N? Both systems are 50 Hz and have the same resolution, so it should work somehow. Thanks a lot!
