  1. Good point. I wonder if the Pause, Select, Reset buttons should be avoided as well? The game would work perfectly well with a choice easy/hard at startup. But to abandone a game and start again I believe the Reset button could be nice to implement.
  2. Thanks for the idea. I was hoping to keep the game withing 32k and TIA. But I have to experiment with the overlay idea. Anyway the game is now playable. And the TIA music in enjoyable (imho). The tune is written in Furnace Tracker! So here is a real Furnace Tracker TIA player in action. But there is still basic stuff missing like: Left difficulty switch to control 1 card (Beginner) or 3 cards (Advanced) at a time. Re-start the game by shuffling the deck. (Reset) Choose colours scheme. (Select) Plus I would like to support paddles also. The joystick may not be the best option for control. The cards are actually in lists and rotating the paddle is a way to scroll through the list. The first 6 cards on top would start the list. Followed by the 7 piles.
  3. I bought one "anything to HDMI" converter for €36. The instruction booklet was from a hair dryer and the box had a lot of spelling mistakes. But the product worked ok. So my guess is that just try your luck and buy a cheap one.
  4. Thank you. My playing area splits the data in larger tiles and I thought of re-using that structure for the title page. I guess that the big job is going through the graphics, choose the palettes, edit away colours that cannot be shown. I also tried posterizing the image to reduce the colours. Something along this line may be doable in the few days I have left before Easter. I just realized that the easiest way that still has acceptable result is to change the image to greyscale, colorize it and then I will add highlights in white manually. But thanks for the suggestions. ... and keep your eyes open for the Easter release
  5. I am trying to make a small silly game for the Easter holidays. It is already working. The music is written as well. But I would like to create a small title page. The problem is that I prefer to use the 160A mode and I have place for 42 tiles at the size 24 x 16 pixels. So basically I have 7 * 6 tiles to work with. Right now doing the work to choose the palettes and map some graphics to the tiles feels a bit too much. Is there some hints of what tools to use? The idea is to duplicate the lines to produce a 224 line image. But is this even doable? The image I am trying to use is this one. It has just 16 colours.: So at least I have to get rid of 7 tiles to fit the image in th 42 tiles I have. Edit: I could cut away the last line. That takes care of the number of different tiles. Then the remaining task is to find the palette to use for each tile. There is just 7 palettes, I assume. And to reduce the number of colours to 3 per tile plus the background colour. Which is probably yellow. Edit2: Or perhaps I get better result by just choosing 4 colours and drawing the chicken by hand...
  6. For most of the games emulation is good enough. I really hope that the 2600+ would become a "good enough" machine for all the 2600 and 7800 titles. I really love the fact that it runs real carts and that it can cope with NTSC and PAL. This is something my original 7800 PAL machine can not do.
  7. I just received my adapters and updated the firmware. So far no complaints. My carts just work. One thing I do notice is how outdated the music of the games are compared to modern games. Less is more for the Lynx. I have to try writing less irritating tunes in the future.
  8. The whole pcb in KiCad format is there. You can plot the gerbers if you want. Or get pcb's from me.
  9. You will not be able to run any 7800 games on that cart. It lacks the 7800 signals. The resistor is likely 10k pullup for the switch.
  10. The cart is great for running some homebrews and most 2600 titles. For many titles you need an external powerbank. Some high speed titles makes the pico run very hot. The games may crash...
  11. The critical part is the amount of RAM. The flash is too slow for being run at 400MHz. Many homebrews won't fit in the 256k of RAM available.
  12. The Pico overclocked to 400MHz can still not react fast enough to some bankswitch modes. The chip is already too hot and would require active cooling. A better alternative is to use a real memory chip for simulating a rom.
  13. Pico is a nice tool for emulating carts. Unfortunately it cannot compete with a real fpga implementation.
  14. The tgi is really not used for text anymore. I am usually using a smaller version without any text functions. mini-tgi.s The way to contribute would be to write a new display function to replace tgi. Something more optimized that would only include the used functions in the binary.
  15. I get your point. The higher pitched tune sounds nicer in a way. I have been thinking on setting a 2nd note on the few tones that are off just to mask them out by adding a ters in harmony with the offending note. But first I want to see if I have time to compile the code for my springtime surprise game! Easter is already on the 31st of March... A 2600 version would probably need extra RAM for keeping the card piles. So some kind of SuperCart would be required.
