METAL SLUG ANYONE?

[baorder54]

Dude bananaman, we really need more poelple to join. we need to get organized, i mean look at sonic. We dont wanna end up like that. But we gotta get the spark into a flame, u read me?

I'd help, but I'm only beginning to learn ASM. Looks good though.

[baorder54]

Hey were all learning more asm here. thisis my and banamans first scroll project so. But ya anything helps. Heck if u could pump out some sprites thatd be cool. Or research levels. Idk but anything helps.

[Cure]

I could probably help out with sprites and level design.

I guess this would be a good learning experience for me.

As I said on the other page, I will help you to optimize/debugg if you post parts of code and tell me what are the supposed inputs/outputs. Just ask!

Cool if u have calc gs cool if not heres the link below. This is a good tool for making sprites animations, and maps.

Calc GS


Btw I was thinking of taking a google pic of metal slug logo(search: metal slug logo) and using this tool to make it a pic. Im not sure how this prgm works but heres the link to it.

Linkadink for istudio

The metal slug logo should stay black and white i think but fool around with it.

Ok, it's not very complicated:

To have good GS effects, then use interrupts in-game and fixed code in menus while using multiple layers. Note: as the LCD driver changes with calc versions, the greyscale that might look perfect on 1 calc might look really bad on another (I experimented).

For IStudio2, it is very simple of use. Save your color image in a .bmp format. Open it in IStudio2. Select the greyscale level you want and the output format (you want .db Z80 format with no compression, for now). Then click ok and open up the output file in notepad. Here you have your picture converted in code, ready to re-compile in your program.

You can just play with colours in paint, or with This program of mine, which lets you draw 4 level Greyscale directly on your calc and then hex-output it on your calc, then transfer th .8xp file on your computer and then copy/paste the code in your source code.

But for a image that is supposed to take up the hole screen is that too much?

[Fallen Ghost]

No. The picture's format should be 96*64 (screen size) so it gives a fiole-size on-calc of 768 bytes. Then, if you want 4-level greyscale, you'll need a second layer, that you will need to exchange with the first one very fast continuously. And if you want 8 levels, then you must have 3 layers, and therefore 2304 bytes in total (768*3).

If it is your title screen, then definitely not, it's a title screen, which is basically only a 96*64 image. For your menu, you can just draw your menu options inside your image and then make a selection highlighting or something like that.

Note: I know my program (drawgrey2) is ugly. I did not develop it to be nice, but to be functional and memory-wise.

Did u look at the bottom?

We can give "Carl" all the credit we want for ripping the game sprites, but it's still Copyright © 1996 Nazca Corporation.

ok... thanks for that...

[bananaman]

Are you planning on doing this in grayscale? If we are going for speed and fast scrolling it might just make it too slow, or really ugly looking on the calc. Look at the robot war screenies, black and white can still have awesome graphics. Also if you go to maxcoderz it appears that someone is creating a top down shooter.

[baorder54]

Because metal slug has so many sprites/ intense background/ objects on screen, i thought about one grey, but everyone on irc confirmed it would be slow. I think that because this is such an intense game, we cant afford gfrey but maybe later if for saome reason our game is lightining speed.
