Quote from: Gryzor on 09:33, 11 August 21What's smart about it? Does it have a custom made board in it? Is it programmable in any sense?
Quote from: eto on 11:47, 11 August 21Nothing smart about it. Just a NE555 and a jumper to select Atari vs C64. However it's not clear if there is a specific Amstrad version. I would expect they simply shipped the Atari version and nobody ever recognized the secondary button issue as rarely games used it.Code Select Expandhttps://youtu.be/myyJnqXWbdg?t=504
Quote from: eto on 18:25, 11 August 21On the Amstrad fire button 2 is on the same line as VCC on the other systems. I guess it's more like a side effect of the circuit rather than intended, that button 2 is "pressed". The seller is not probably right that it works in games, as pretty much no CPC game used fire button 2. So even if it triggers the secondary button every now and then, no game will recognise that. However this is no longer the case, since many games have been patched for 2 button gamepads and there, it will fail.
Quote from: Vyper68 on 22:50, 11 August 21There is a teardown video on YouTube and the PCB seems to have a variable resistor and a 555 timer and a few SMD resistors. So I'm not sure how they would configure it specifically for an Amstrad.https://youtu.be/myyJnqXWbdg
Quote from: chinnyhill10 on 00:59, 12 August 21Even if the game doesn't recognise it, it seems to slow down the input. For example movement and fire seem laggy presumably as if you press a direction or fire at the same moment it decide to spew out a random "Z", your intended input is fractionally delayed.
