Sharp MZ

EN: Good morning all, Here is my last replica: the MZ-1E14 Quick Disk controller for Sharp MZ-700. I had a little trouble finding the contents of the EPROM as it does not exist on the official site or on the old one. The interface worked perfectly the first time and is based on the diagram in the MZ...

Hello,

I am looking for MZF or MZT files containing programs in BASIC of the Hu-BASIC type to have examples of programming in this language.

Thank you.

Possible! Not having analyzed the complete code of s-basic 1z-013b.
It seems to me that there is a whole working environment in the form of memory locations and that saving this environment is not necessarily essential ... to be checked.

On sbasic 1Z-013b, USR can be found in $3305: USR: CALL $57FD; Syntax check for open parenthesis CALL $4D65; Evaluate the expression (HL) and provide a 2-byte value: Address PUSH DE INC HL CP 29 JR Z, USR_1 DEC HL CALL $3332; Comma syntax check CALL $4DBC; Evaluate the string expression and provide ...

After code optimization I get a wav of 1m33.59s. I doubt it will be possible to do better. I do not know if it is possible to modify the game itself and publish the modifications in view of its publication by sharpworks: I would like to offer a version with choice of more or less difficulty compared...

I'll try to optimize the code, since it's a compiled program so there is some headroom, and maybe I'll reduce the size significantly further.

In this version, the decompressor is part of the code, it is not integrated in the header of the MZF.
In the decompressor version in the header, we have a wav duration of 99.1s (1m39.1s).
The difference is not visible when loading.
For information, the delta is 3.

After compression with mz7, I obtained a wav file with a length of almost 100s (1m39.58s).
It includes the initial presentation screen, the one displayed during loading, then the welcome screen with the rotating banner, and the complete game.

I didn't compress anything, the file is 45.6kb in size and has been recompiled so that it can load all at once, so it takes that long in wav. When using a drive other than a tape drive (in digital therefore) I find it more practical to have a single file rather than 8. Given the structure of the dat...

If anyone is interested, I recreate Beyond as a single MZF file allowing it to be loaded more easily on a real machine and an emulator.
