Great, it's working now.

Had the demo back in the early 90s (possibly 92 or 93) along with a +2a (black, not the one I have now) on a 14" colour portable. Bicie demo definitely produced beeper sound on the second option - I recall the AY sound being better than the beeper.Woodster wrote: ↑Thu Nov 21, 2019 2:48 pmSo the +2A (and presumably the 128K too then) produce audible MIC output through the TV speaker with the Beeper bit off? The reason for the silence in SpecEmu is that it's stated in the FAQ (or at least somewhere :p) that the MIC output alone can't drive the speaker but can be used for a slight increase in volume when used with the Beeper bit.
On a real Spectrum (all models), toggling either the MIC or the EAR bit of Port #FE will energize/de-energize the beeper. On 16K/48K Spectrums, it is physically the same pin of the ULA; on 128K machines, there are two separate ULA pins that are either shorted together (128K/+2) or connected via resistors and decoupling capacitors (+2A/+3).
It's a simplified version of the original game with a different map I made earlier as a test, prior to next and definite development of Aquanoids.
Thanks hik and Neil. I looked into this, but I couldn't work out exactly what the reduced version was, and if it should be added to the archive. I also didn't add the main version of Aquanoids, I think because it was a commercial release at the time. Should I add both to the archive?Neil Parsons wrote: ↑Thu Dec 05, 2019 6:13 pmIt's a simplified version of the original game with a different map I made earlier as a test, prior to next and definite development of Aquanoids.
Whenever I can, I'll provide the TZX file of this Aquanoids Redux.
