Metal Slug (Mission 1) port for Atari STE - Completed

[masteries]

This is the definitive Metal Slug (Mission 1) port for Atari STE
-Using Atari Game Tools, almost all the game is programmed using C language

Features:


-Complementary Dithering colour, aprox. 70 colors on screen; requires more than 40 frames per second. As emulator, Steem in the recommended one, and activet Vsync


-652 KB of digital sampled audio, 3 voices mixed at 12.5 KHz
Music is also based on sampled audio loops at same frequency


-Around 3 MB of graphics data


-50 frames per second gameplay, few slowdowns


-Hardware requirements: Atari STE @ 8 MHz CPU + a hard disk device

Unbelievable This is stunning work

[EzdineG]

Amazing! Thank you!

[chlu600]

Thank you for this release.
You have done an incredible work.
Such efforts gives hopefully dml (author of ATG) energy to continue the development of ATG

It gives the whole Atari community good vibes

I've tried this in Hatari, but the program does not react either to keyboard, joystick in port 0 or 1, or joypad in port A or B.

Same thing both with EmuTOS and TOS v1.62, and whether mslug.prg is started from AUTO or desktop.

How one is supposed to control it?

WOW

W A S D for movement, M big jump, N fire, B grenade

seems to work on a real STE

Hi,
I hear several users with problems starting the prg.

Starting from harddisk in GEM gives a frozen and black screen after generating all sprites etc. Same result with Auto folder. Problem verified by several users.

Do you have a clue?

[Fatberg]

Excellent work and a great port of a great game!! Plays well on my 4mb STE, using pp hd driver.

Yea about that,how did you load it, tried on my STE but just end up with a black screen after some preload of sprites or something
? Or are you using some weird modern gotek stylish big pseudo drive?..I mean a 3 megger dont fit onto a normal floppy
I moved the main program from AUTO to main directory,it starts and loads some stuff.Then just sits there.

TOS 1.62 on 4megs.Pretty much just AHDI loaded into memory.

edit,A bit lazy just now so didnt check in debugger or anything.

Tested on TOS 1.06 and TOS 1.62
Using my manufactured hard disk unit and Peter Putnik driver.

As well, designed to be loaded from AUTO folder, without any other thing into memory (despite P. Putnik hard disk driver). All is ok in described way,

This is the price of Neo Geo quality, you need almost all available RAM, and very well optimized drivers such P. Putnik one.

Amazing work ! Congrats !
If only we've had such STE games at the old times

Muchas gracias Masteries

Works fine with EmuTOS.

Last things the game says before level starts are:

Code: Select all

creating world...
assigning world map...
assigning world tiles...
assigning buffer 3 world tileset...
assigning buffer 2 world tileset...
assigning buffer 1 world tileset...
assigning buffer 0 world tileset...

If there's only 2MB ram, it stops much earlier while loading assets, and with 1MB it does not even start loading the assets after pressing space. So the issue could be memory use even with 4MB RAM. Try to strip all the extra memory usage out (no ACCs, no desktop etc) before starting it.

The game / level is a great achievement, but as game it is *really hard*... It's good that there are infinite lives.

I guess level end is with the machine that shoots light balls, as that scene is somewhat broken. Jumping to top right from top right platform drops player below screen. And the machine can get broken so that it does not anymore shoot those balls, but it does not take any damage from player either.

Since you put it that way,loaded the stuff into debugger and it runs into div zero at $68444 and when searched a bit memory there is just zeros after $e0630,,ie non used memory until usual memtop of course,plenty of space even with driver and debugger loaded.
And reading some more into what folks are noticing, maybe 4megs is something to handle?
After all its just to load into what free ram is available,maybe a hickup in memory handling code?

When using Hatari and AHDI5, I had to boost the ST RAM to 8MB in order for the game to start. I also copied MSLUG.PRG from the AUTO folder to the program folder. Otherwise, I would get a black screen regardless. When I used PP's hard disk driver or EmuTOS's built-in driver, I was able to run the game with 4MB. To be fair to AHDI, hard drive installable games weren't a thing when it was developed.

impressive result (I just watched the video)

Mine is running on my real STE, with 4MB RAM, UltraSatan HD, running from an SD card with PP driver. Game running from the auto folder.

I couldn't get it to work without running it from Auto. Perhaps not quite enough memory left.

I experienced the same thing with the ending, destroyed (well stopped it shooting at me) the big double cannon thing at the end then trying to figure out where to go next I fell off the screen.

[manicx]

I successfully run it. Specs

STE 4MB
TOS 1.06
UltraSatan External
PP driver (registered)

Just copied the files to an X partition and switched to that on boot time. The game runs well and it is VERY impressive. A couple of times it froze and had to reset the ST (see pic below). Otherwise, perfect.

There is no more on Mission 1, you reached the end.
Final boss is exploding forever xD

hmmm... these sort of failures are typical when any of the sprites data is bad loaded,
due to all sprite frames contain specific 68000 code, and any minor defect produces bombs crashing.


Despite this, due to you are using a CRT monitor, the complementary colouring shall work in his best fashion!

Excellent. Impressive work.

Were you able to re-use original logic code or do you had to reimplement it from scratch ?

Some kind of "The End" text at that point would be nice. And a little doc in the ZIP telling the keys to use for control.

Do not really see where. Is it a problem to repeat something ? The fact the new code in developed in c does not mean there is nothing reused as is somewhere... (in particular as neo geo is 68k based)
