Re: Gradius II Japan Not Booting? [Solved]

Same problem with "Bio Miracle Bokutte Upa", although in this case you have to play for a while to make the game crash (two or three levels).

I have reported it on github, hopefully it can be fixed for the next release:

Re: Add an Overclock Option to Avoid Slowdowns

Hi, I am not expert in NES, but it seems that NES have all it's timing related to the main CPU. That is the reason why NTSC and PAL NES have different working frequencies. With an Overclocked CPU, video timings will no longer be accurate, and sound will be faster and higher pitched. More modern systems have separated clock signals for sub systems,...

Re: Add an Overclock Option to Avoid Slowdowns

I understand it, but other cores like gba, megadrive, snes, and some arcades implement this functionality. It's true that some games don't work properly, but many others work without problem. I don't know if in these cases only the cpu or the rest of the system is overclocked, but for practical purposes it's functional and an improvement when playi...

Re: Add an Overclock Option to Avoid Slowdowns

yes, I always have it on, I understand that it eliminates the flickering of the sprites when the limit is reached (8 sprites per scanline), I think it doesn't affect the speed of the cpu / ppu at all, and if it does, with this option active I still notice slowdowns in many games.

Add an Overclock Option to Avoid Slowdowns

Hi,

Would it be possible to overclock the core to avoid slowdowns in games like megaman, double dragon, gradius, blaster master, ...?
It would greatly improve the playability of these and other games.

Re: Spectrum core: Fast Tape Load problems with TAP files

yes, if the fast load option is disabled and the tap is inserted before the load command, there are blocks that load accelerated, and sometimes it gives a tape loading error.

Re: Spectrum core: Fast Tape Load problems with TAP files

Tested again and with core version 210427 D+ & mister v210419, contended memory test loads at 100% speed without errors. Of course, I have to first input LOAD "" and then insert tape and press F1 to force each block loading manually. Maybe it could work in a more intuitive way, but it works. It is true that if the fast loading option ...

Direct snapshots for spectrum core

Hi, It would be interesting to add an option to save snapshots directly from the core, in z80 or sna format. I know that the core implements the emulation of Disciple and Multiface and that they allow dumping snapshots to disk, but when used to save game states, managing these in a comfortable way is complicated, in addition, some games has crash o...

Re: Spectrum core: Fast Tape Load problems with TAP files

try loading in reverse order, first input LOAD "" and then insert the tape. In this way it loads at real speed, and if the load stops, press F1 to continue.

Re: ZX Spectrum April 4th 2021 TAP loading not working

Seems to be a problem related to new keyboard issue selector, when issue 3 mode is selected tape loading works perfectly, when you select issue 2 there's not loading at all.

Re: Blinky's Scary School menu don't work

ops, it's true, i've tested my abu simbel version and probably it's patched for issue 3 because it works with these changes. I reopen github issue to see if anything can be done.

Re: Blinky's Scary School

Thanks for the info. As soon as i've played audio across the adb port, the game has worked perfectly. I have also tried to replace CP values next to IN A,FE and it works too. It seems that bit 6 is set always to 1 if no audio is received from adb input. Maybe someone who knows the code can add a menu option to change this behavior.

Blinky's Scary School menu don't work

Hi,

I've tried different combinations of settings and game versions to play Blinky's Scary School in spectrum core, and none of them works for me. Tested 48/128k mode and tap/tzx/sna tosec files. All of them get stuck in the main menu and is not possible to start playing.

Does it work for you? Any suggestion for compatible settings?

Thanks ;)
