Re: ZXBaremulator 3.2
Today I continued testing BM 3.2 and found some rough solution how to avoid (mostly) that buzzing sound. I noticed that after each reset with CTRL + Break, the buzzing stops and then I can enter the menu with F1, select the game and go back to the emulator, without that sound issue. It’s not too el...

Re: ZXBaremulator 3.2
Can't find Paralactika demo in tap/tzx format, to test it on 128k models, I only have a trd version. I saw in soime youtube video "paralactika_zx128" or something like that but the author did not leave a link. Can you share some download link for that version, which you used when testing ...

Re: ZXBaremulator 3.2
The problem with the buzzing sound is that I can't reproduce it on my TVs. Could be that some TVs aren't happy with the 32 kHz sampling rate I use. The ZX-Uno is dead. I own one, sleeping in his box. Nobody develops cores for it. Now, you can choose a MiSTer, Mistica or SiDi. But don't exist a FPGA...

Re: ZXBaremulator 3.2
The ZX-Uno's Spectrum 48k core is basically correct, but the contended memory timings is wrong on all cores, all FPGA's I know. The 128k core isn't complete and the FPGA PLL can't generate the needed CPU freq. for the model (is off by 8 kHz). The +2a is the same core than 128k with the +2a ROMS. Ho...

Re: ZXBaremulator 3.2
Maybe another option is to release the source code so maybe other enthousiast can continue. Unfortunately I'm not a very skilled programmer but maybe someone else is. Some "smart" guys on eBay are selling ZXBaremulator and BMC64. I don't want to get any money from my emulator, but I don't...

Re: ZXBaremulator 3.2
I would just like to get rid of this buzzing sound, which we talked about earlier. I don't know if you had time to investigate it, I just have this problem on each of my 3 pi models (2, 3, 3+) and I haven't been able to eliminate it, except using the old v2.0 version, which doesn't have a GPIO keyb...

Re: ZXBaremulator 3.2
I think the PI2 is the best option. It does have sound over HDMI and it's more than capable of running the emulator at full speed. A pi3/3B etc. is a bit overkill for just a spectrum. The only one advantage from a better PI is a faster "fast loading". The HDMI sound support needs more CPU...

Re: ZXBaremulator 3.2
I'm interested to know if it's possible. You can edit the config.txt on the ZXBME Sd card.. use hdmi_mode=6 If you are on hdmi_group=1 , mode 6 is a 480i (4:3) mode. You may find the stretch on your TV will work properly then. More info of HDMI modes here : https://www.raspberrypi.org/documentation...

Hi @zx81, Very many thanks for ZXBaremulator 3.2. I tried it for the first time today, and I'm very impressed! Nice work. Thanks. Can I ask a few questions.

Re: ZXBaremulator 3.2
Thanks by your investigations, Pegaz. The 'amixer' command is an ALSA command, so only works under Linux. As I said before, all the video/audio management is done by the PI firmware at boot.With a HDMI TV connected, sound outputs through HDMI. When no HDMI TV is connected audio/video are redirected ...

Re: ZXBaremulator 3.2
Is this a Pi3 A+ model (I have one), which normally sends audio and video through hdmi? What makes it necessary to take sound/video from audio jack or GPIO connector from it, then? The PI firmware chooses one when the board boots. When don't find a TV on the HDMI connector, switch the image/sound t...

Re: ZXBaremulator 3.2
From the start, the idea was to use the same pins that printed in MagPi #67. Many people have his circuits wired like these, so I can't rewire the pins without cause problems to some users.

Re: ZXBaremulator 3.2
Hi Jokin,
No, I'm sorry, the Zero have reserved all GPIOs to keyboard handling.
Really, a Zero isn't the best option to run ZXBaremulator. The best choice is 3A+ or the cheaper A+. With 3A+ you have HDMI sound, and with A+ you have PWM sound.
Thanks by test my humble emulator.

This V2 rom is compatible with all Interface 1 versions? I've seen that ULA types are LA-15-302, 312 or 311. Is the rom image compatible with any of these? I guess yes, are compatible. The main change from V1 to V2 is the format method, that reduces slightly the cartridge capacity but gains in reli...

Hi MonkZy,
Thanks by your kind words about ZXBaremulator and by share your build with us.

Re: Crashing Super Wonder Boy
Excellent work!
But the patch references to a release with SpeedLock 7 protection, and my copy of SWB is SpeedLock 4 protected. Is an error in patch comment or anyone have a version with SpeedLock 7?
