I don't think the problem is a specific zx max performance, the game doesn't use any cheats of the original hardware. I think the problem is some kind of base problem, like a memory fault.
Hi! Snapshots store information only about the current state of the Spectrum, it does not know about the tape from which it was loaded and from where to continue loading. If the whole game fits in the Spectrum memory (like the first part of Neoplasma), so there is no problem with it. But if additional downloads from the tape are required, the game just doesn't know where to get them from.
So there are two options:
1) pass all three levels at once without using saves. then at the end of the game you can register a QR code on the site to record your progress in the record table.
2) at the end of each level you are given a password, with the help of which you can skip this level next time. but then there will be no QR code at the end of the game, because the password is too small to encrypt the progress of the skipped level in it.
It's very sad that you didn't like this game. I really don't understand what "pixel perfect with jumps, shots and grenades" you are talking about. The level design is made for beginners players, with no special experience in platformers. Mostly players on the contrary complain about the lack of difficulty.
Hi! Many emulators and devices for converting TAP to sound, make the pause between files too short. I added TZX folder to the ANP2_v1.6.1 archive, try to get the download file from there.
The game does not work in newer versions of CSpect because bit 2 of register #22 does not turn off the original ULA interrupt. That's the main reason. In the old version of CSpect V2.12.36 this works properly, you can play the game in it.
The second point is related to copper co-processor, sound effects are not playing correctly because of this. So far they are not reproduced correctly in any version of CSpect.
In trd and next versions password is not needed, because after passing the level the game saves state to disk, so you can continue the game from the same level after turning off the computer.
Yes, that's right, because you don't enter the password to "load" the desired level, but to "skip" the level (don't forget you're dealing with tape) i.e. first you enter the first password, load the second level, and enter the second password, and load third level.
