I need help

#1 Post by Emiliano Fierro » 16 Nov 2019 20:26

Hello everyone 🖐️
I am new, my name is Emiliano Fierro and I am very interested in retro games
Recently I had a problem with hex codes
I want to convert some hex codes to the codes used by MS-DOS
I hope you help me
David was not clear in his explanation so there are two options in 2 cases

Could you give some more context information and also link to the post(s) you are referring to?

Intuitively i would use environment string manipulation for that (but that might be suboptimal in your code; untested alphanumeric example):

Code: Select all

@echo off
setlocal enableExtensions disableDelayedExpansion
set "table=                                                0123456789       ABCDEFGHIJKLMNOPQRSTUVWXYZ    _ abcdefghijklmnopqrstuvwxyz"
echo(%table:~0x30,1% to %table:~0x39,1%
echo(%table:~0x41,1% to %table:~0x5A,1%
echo(%table:~0x5F,1%
echo(%table:~0x61,1% to %table:~0x7A,1%
goto :eof

I come from another forum of The game Prince of Persia
But I will not give more details
So I wanted to change some colors and asked for help, David answered and was not very clear
Today in the morning I used a hex editor and did what I needed
But I still want to learn to use MS-DOS

Seems you are actually talking about DOS. Can't recall what opportunities you have on DOS to change binary data. But I'm afraid you can't do that using Batch scripting.

I'm pretty sure the only option for something that old is DEBUG.exe

Umm, from HEX to binary. But if you are able to use a HEX editor wherein you change the original binary file then the changed HEX values will be automatically converted back to binary as soon as you save the file.

Thanks
Do you know about any code converter?
The thing is that I want to make the files since 0

No. If you want to program the binary file you need to get the source code and learn the programming language used. The program to make source code to binary program code is called compiler.
To program your own game is probably more than two years of intensive learning ahead of you though.

I need another format (not the binary)
I need this other format
Look at the example of the binary code

Just consider that I'm not a programmer
I want to learn more about codes
One day I will become an engineer and I want to make my own games for the MS-DOS OS and open them with DosBox but nobody will teach me
aGerman: Right, I won't send you any PM like “answer my post” or so
This is why I need a code converter

The subject of this forum is Batch scripting. Please explain what your question has to do with it.
