Some games' AY players are synchronised with the game's frame generation (which can be slower than the TV frame rate); some others are interrupt-driven and hence they run at a constant speed. That's normal.
From the above posts, it appears that Rainbow Islands uses the former method, while OutRun uses the latter.
I guess that for the Next it only makes sense in 48K Spectrum mode, just like in the 128K and later models. I may look into it in future. I thought it wasn't very useful because you can type the commands letter by letter, so any keyboard would do, but after all it's also 48K-compatible so...
Does it make sense in the first place?
I didn't even try because I didn't think it did.
Thanks, I've also updated the status of molekula's other core, the MSX1, which I believe is official for quite some time now and was still listed as unofficial.
Oh right, I should learn some reading comprehension >.< Sorry.
As a remainder, it's possible to have up to four different MiSTer.ini files: MiSTer.ini, MiSTer_alt_1.ini, MiSTer_alt_2.ini, MiSTer_alt_3.ini and switch between them using the same menu where you change volume.
I believe that XDF and HDM are the same format, so you can try the Python hdm2d88.py program in my sig.
Maybe post here for help?

I'm not sure, but it appears to be a Main_MiSTer thing.
Amazing research work, JamesH! Thanks a lot for filling in all these blanks.
Nice find about Genie 128, I didn't know that one. I wonder if it's a leftover from a time where it was used to debug the core, and when it stopped being needed, only half of it was replaced with another ROM and the other half remained.
See viewtopic.php?p=60600#p60600 and the post after that
This subforum would be a good place: viewforum.php?f=14
If it passes review, maybe it can become official.
I was always intrigued by that computer, by the way, when I saw it in ads.
I think certain cheats require that. I'd have to look up which ones.
And, well, if it can't pass a keyboard test, it feels less like the original machine. The creators of the Recreated ZX Keyboard considered it important enough as to drive the design of their protocol.
Thanks for the detailed explanation, macro! I love these kinds of details.
This looks like one of these cases where FPGAzumSpass' technique of making a software emulator with a view on the FPGA implementation before actually implementing it in Verilog could pay off. The compile/test cycle for trial-and-error would be much faster.
I don't think so, but you can try the following:
diff -qas <path to 1st core> <path to 2nd core>The last command will tell you whether they differ.
Comparing to MAME, I think the difficulty switches may be reversed.
The integer scaling option already cuts the borders a bit, maybe not enough though.
Wow, now I can enjoy this Bandai classic with unprecedented response time and zero lag!
Joking aside, this is awesome. Thanks a lot for this core. I just miss the possibility to disable autosave, because I open the menu often and autosaving every time will cause quite some wear on the SD card.
