RPV2000 Posted March 16 Share Posted March 16 I had a chance to build both of these flash carts, and they both work awesome. Thank you both so much for your hard work and willingness to share with everyone here. I have one question about the 16 in one multi-cart for 2600 only games. I had read that you were working on a feature to switch games using an IR remote. so when I built my boards I soldered on an IR photodiode with a 300ohm resistor. I recently read in this thread that this wasn't for the IR read to switch games but simply an LED power indicator. Is this the case? 1 Quote Link to comment Share on other sites More sharing options...

I recently read in this thread that this wasn't for the IR read to switch games but simply an LED power indicator. Is this the case? I have mine with an IR photodiode as well and a some demo-code that is close to fully working. I've been having some troubles with stability when trying to run the cart and checking the diode. I have the ROM part working on 1 CPU and the photodiode on the other, but there still seems to be some hiccups, maybe related to interrupts that will cause the ROM emulation to miss a cycle and mess up the game you are playing. Hopefully I can get it working. Quote Link to comment Share on other sites More sharing options...
+karri Posted March 20 Author Share Posted March 20 Happy springtime! In order to celebrate spring I wrote a small Easter game. Well, it is just a Solitaire called Klondike. But with some chicks added. Here is the game for the Otaku card. Easter.uf2 Enjoy! This soundtrack is my 1st attempt ever to use Furnace Tracker with TIA. I am really surprised in how well it turned out. Thanks to @Dave C for writing the experimental TIAdriver and Furnace Tracker TIA rom export!

pseudografx Posted March 20 Share Posted March 20 Not bad for a first attempt. Perhaps try adding a bass line? Quote Link to comment Share on other sites More sharing options...

Percussions or bass line is the choice to make. Or some kind of instrument trickery where you can get two sounds of one note. Quote Link to comment Share on other sites More sharing options...
Gamemoose Posted March 20 Share Posted March 20 What's the song? It sounds like Axel Foley's rendition of the "Dating Game" theme from "Beverly Hills Cop 2". Quote Link to comment Share on other sites More sharing options...

It is a tune called Spanish Flea. Written by Julius Wechter in 1965. I am playing it with my band every now and then. 1 Quote Link to comment Share on other sites More sharing options...

+karri Posted March 21 Author Share Posted March 21 Inserting a new sound would cut the current sound. So I don't feel it would make the tune better. But I get the idea. Quote Link to comment Share on other sites More sharing options...

Interesting. I have no idea of how to do it. The tune I wrote is written in Furnace Tracker. I wonder if you could take a look and see how to incorporate the bass. I have the bass line in the pdf. Spanish Flea.pdf The Furnace Tracker file is here: TIA_Spanish_Flea_Effects.fur Edit: I found an article in TIA Tracker talking about "Overlay percussion". The idea seems to be that you play the percussion on the beat and skip the attack phase of the following melody note. So a bit like the forever argument between the drummer and the bass player. It is more than one once I have seen a drummer trying to sell the bass player after the gig as the bass is always late. So now we have a "well-known" technique to do this properly . Just kidding. I will spend some time in creating a combined bass-hi-hat instrument to try this technique. 1 Quote Link to comment Share on other sites More sharing options...
+karri Posted March 22 Author Share Posted March 22 Ladies and gentlemen... (drum roll...) Springtime greetings! Here is the fixed version of Easter Klondike: Easter.uf2 Reset: starts a new game Reset: exits a game and shows the score Select: allows you to choose the game while in the title page - 1 (easy, draws 1 card at a time) - 3 (difficult, draws 3 cards at a time) Fire: choose cards, drop cards Fire2: draw a new card from the deck, show the face of a card in a spread You can also draw a new card from the deck by clicking on the deck. When the deck is empty you can click on the empty deck to turn over the waste deck to a new deck. Scoring: number of cards in the 4 foundation decks at top right. Unless someting catastrophic pops up I declare the game complete for now. PS. I did create a Hi-hat + bass instrument. But the tune did not sound better imho. So I skipped the idea to improve on the background music. 1 Quote Link to comment Share on other sites More sharing options...

I tried fiddling a bit with the instrument editor and could not figure out how to set an instrument up it in a way I needed. Best I can do is send you some examples of what can be done with just two channels in RMT for inspiration.

+karri Posted March 24 Author Share Posted March 24 I believe that I got the idea. Here is a percussion demo. The Closed Hi-Hat looks like this: Rhythm.mp3 Now I add a melodic instrument without attack. The sound starts with a Closed Hi-hat: RhythmBass.mp3 The technique appears to work with very short percussion sounds. But imho less is more. The breaks are more important than filling the space with sound. So this is not always a desired solution. Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted March 24 Share Posted March 24 Is this strictly 2600+ or did the timings on real hardware get worked out? Quote Link to comment Share on other sites More sharing options...
+karri Posted March 24 Author Share Posted March 24 1 hour ago, Gemintronic said: Is this strictly 2600+ or did the timings on real hardware get worked out? The TIA output is predictable. Furnace Tracker uses Stella to generate it. On real hardware the sound varies a lot. But my guess is that it depends on where I play it. My 7800 is connected to a Philips TV with lousy sound. The 2600+ is connected to a Sony TV with a soundbar. The result is beautiful sounds. My Analogue Pocket experiences really strange sounds when using earphones. And nice sounds when using the built-in loudspeaker. The timings are ok for 2600+ and 7800 imho. 1 Quote Link to comment Share on other sites More sharing options...
+karri Posted March 24 Author Share Posted March 24 I started to play with mixing envelopes between snare drum and bass without attack. The sounds are getting kind of interesting. TiaSnareBass.mp3 Quote Link to comment Share on other sites More sharing options...
pseudografx Posted March 24 Share Posted March 24 (edited) So I figured some things out with help of some skilled Furnace users and I added a bassline (and a snare drum) to a few patterns. Only about 9 orders are currently updated, the rest will be wrong.

The game sound is so much better now. I am also very happy to be able to study the new Snare and Bass instruments. Very interesting changes in the instrument patterns!!!!

tihmstar Posted May 6 Share Posted May 6 Hello old folks :P I'm a bit late to the party, but happed to recently get hands on an Atari2600 by coincidence. Kinda got dragged into retro, decided to build a flashcart and stumbled upon the Otaku-flash. I already built the hardware and will start tinkering with the firmware soon. I was wondering, did anybody build a 3D printable case for that flashcart yet? If not, would anyone be willing to make one and share STL files? I may end up creating a case, but it's not too high on my priority list, as i wanna hack the software a bit first. Cheers! Quote Link to comment Share on other sites More sharing options...

+karri Posted May 6 Author Share Posted May 6 Nice! The stl files are indeed shared thanks to @ChrisKewl. Here they are: karrika/Otaku-flash: A single game flash card for Atari 2600, Atari 7800 and Atari 2600+ (github.com) The parts ending in 2 are a bit tighter. They worked better on PLA on my printer. 1 Quote Link to comment Share on other sites More sharing options...
