Quote from: Philippe Lardenois on Yesterday at 21:20really nice project. Cheap, and easy to build.Nice!
So I did some and design a 3d Box for it.
Would be nice to expand the capabilities (like loading disks or bigger roms) - I would like to have the capabilities but old age...

Thanks anyway.

Quoteyes
- As the README has been updated is it save to assume it's now possible to just drop the ROM images into the root folder?
QuoteNo. They are replaced by ROMSET
- I also recognized that the |CFGxxx commands have been removed. Will they come back?
QuoteNo. It always goes back to default
- Does the PicoROM remember the last selected config or will it switch back to default if it's turned off?
QuoteThe |PUSB command makes the Pico emulate a USB drive, which you can attach to your modern PC to update ROMs,config. Whilst doing this, it can emulate ROMs for the CPC, so the CPC stops.
- what does the USB part do? The doc only mentions "start emulating a USB drive. CPC will stop working".
QuoteSetting ROMDIS high re-enabled the internal ROMS.
- When disabling the PicoROM why do you set ROMDIS to high? Wouldn't it be sufficient to just set ROM to low? I guess a permanent ROMDIS could interfere with other expansions.
QuoteProbably not, since the Pico need to be able to reset the CPC (e.g. when swapping ROM configurations)
- Would it be feasible to connect BRST to RUN (via diode) instead of a GPIO? I think that would then reset the PicoROM and could then free a GPIO which could e.g. be used to add a switch that selects between default.cfg and the last selected cfg.
QuoteSure, as long as you make it open source
- And last but not least, would you be fine with me creating a new PCB that is smaller, doesn't contain the USB and allows to either connect to the expansion port directly or to an MX4 board? I would of course keep the reference to the original project on the board.
Quote from: Anthony Flack on Yesterday at 21:54Just quietly, I think I might be able to provide a reason to ditch Bomb Jack Beer Edition and return to the CPC. I know it won't ever quite match the Amiga for looks, but my ambition was to make the best version of Bomb Jack for ANY system, and... well, people will be able to judge for themselves soon.
Quote from: pollito on 22:03, 25 September 24I tried the same process several times, but it always leads to the same outcome. Do you have any idea what might be wrong?
Quote from: Wobble_master on Yesterday at 22:22Bit more research on here and it looks like it was the last board produced:I've just noticed that on the image shown on here of my board there are 2 chips above the RAM, on my board they are missing?
Board: PT NO Z80329, MC0099A, Copyright 1988
MC0099A board fitted with 2x41464 (64Kx4 bits) chips instead of 8x4164 (64Kx1 bit) chips.

Quote from: BSC on Yesterday at 21:57As part of my research for a fix, I only saw 1 other board like this one and they used it to show the variety of revisions, if memory serves its D1. My 1st concern were the 2 black wires, but they showed the same on the other one I saw.Quote from: Rabs on Yesterday at 17:24@abalore , for these cost reduction boards does the ASIC include the 6845 CRTC functionality?I was wondering what you guys were talking about when reading this thread on my mobile phone without being logged in (so I would not see any attachments).. Anyhow, now I am reading from my laptop and can see the images @Wobble_master attached. I think I have never seen a mainboard like the one in the first post. Is IC101 the ASIC you are talking about? What are IC102 and IC103 doing?
