GUI-based packrom utility

[DaveyPocket]

I'm currently in the process of creating a GUI packrom application. I plan to have this version do everything the original packrom utility did plus additional features such as extracting the hex file from a uze file and being able to change the header in the uze file. I'll share my progress here as I work on it. So far I have the CRC32 checksum calculator working

Uze, I found a little bug in your packrom utility in the "parse_hex_nibble" function

Code: Select all

static inline int parse_hex_nibble(char s)
{
	if (s >= '0' && s <= '9')
		return s - '0';
	else if (s >= 'A' && s <= 'F')
		return s - 'A' + 10;
	else if (s >= 'a' && s <= 'a')
		return s - 'a' + 10;
	else
		return -1;
}

I assume this line:

Code: Select all

else if (s >= 'a' && s <= 'a')

Be changed to:

Code: Select all

else if (s >= 'a' && s <= 'f')

Ah, right, indeed...funny no one had issues before. Guess it's because HEX files are always uppercase. I've fixed this and committed the changes.

Thanks for the find!

Alright I got something you guys can play with now. All the application does at the moment is load a .uze file and display the name, CRC32 checksum, and a messed up year

Sorry for any Linux and Mac users out there, you'll just have to wait.

Cool! Is it done in .NET? If so, it should run well with MONO under Linux/Mac.

Yes, this program uses .NET framework. I was thinking of making native Mac and Linux programs eventually, might even redo in Java.

coding multi platform apps is really a pain with OS tools. I gave up trying when working on a map editor with gcc+wxwidgets. Ended up with doing it in C#...boosted my productivity by 10000% at least!

Version 0.2 is ready!

-Fixed year (I realized date was stored "backwards")
-Author now displays
-Description now displays (I don't think any of the games have descriptions in their headers)
-Added icon support (Again, no current games utilize this)
-Program size displays
-Added saving function. Try not to save anything just yet, the header gets duplicated. So if you save, your game will have two headers!

I included a sample .uze file of Arkanoid with a modified header. This sample includes a description and icon which appears as garbage (randomly typed in values from a hex editor )

Enjoy!

Awesome! For sure there's a lot of fields unused, but with such a tool it will make it so much easier to fill them up.

This tool will have to be part of the official tools for sure. If you don't have access to SVN, just pm me an email/gmail account and I'll add you to the project commiters.

I'd be curious to know if it runs as-is under Linux with Mono. Anyone to test that out?

I love C#...and I'll give this baby a whirl under Linux tonight (I was planning on setting aside some time to work on my game anyways...so this helps!)

Thanks for the great contribution.
