The Great Escape - final release

Recommended Posts

I am really proud to present final version of The Great Escape game part for Atari 8bit!

 

Thanks for people who helped me with the port (in no particular order):

Jose Pereira: loading screen, credits screen, pm/g overlays in-game

Philsan: title screen

Poison: title music

Wieczór: in-game sound effects

 

Game requires 64KB of RAM in order to run. Game is both PAL and NTSC compatible. Final version was tested on Altirra only, but it should run properly on real hardware. Music uses stereo Pokey, but it should play on mono Pokey as well.

 

For those who didn't read WIP thread: game is ported from C64 version, however code is optimized and is also using Atari hardware features, so performance is roughly 3 times better than it was on C64.

 

 

Enjoy!

Just a side note: Loading screen similar to ZX's version is on the .atr and yes, even simple there's ways to in some cases we on A8 have hi-res screens with some colour while loading.

:)

It looks that the version I have posted has some last-minute bug, which causes graphics glitches in-game. Here is proper version of in-game part which has fixed gameplay. I will work on update whole release later.

Great job!

I remember this game on CPC 6128. Scroll and performance were terrible..

 

But where is the flag in Atari version? ;)

Here is bugfixed version of the game. Graphics glitches in-game are now fixed. Turned out to be decompression issue.

 

Please test this on real hardware and let me know if everything works properly.

This is Atari, so performance is good :)

 

The flag is missing, as it was not present in C64 version. Sadly, the searchlights in the night are missing too, as C64 coder didn't bother to implement them :(

Hmmm,

 

did the version from post #3 still have the gfx glitch ?!? You said the glitch was due to the compression routine, but the attachment in post nr. 3 came uncompressed... (so I guess it did not have the gfx glitch, but I am not sure)... ?!?

 

Besides, most Atarians do not like the C64, but for such conversions a C64 webpage with manuals and solutions is quite good. Here are some manuals and solutions for TGE, read the solution(s) only if you are stuck or very impatient... (like me). And errmm, I already converted the text into ATASCII (max. 38 chars. per line), so you can read it on the A8 if you like. Hopefully the game did not change in any way and the solution for the C64 is 100% the same for the A8...

Only the version from #1 has glitches. Other versions are fine.

 

Gameplay should be 100% the same as C64 version. Gameplay code was not touched at all, only rendering and scrolling code was changed for Atari. If you manage to win the game, please let me know.

Wow great port! :D Smooth (not that I'm surprised this is the A8 ;)), now I just need to remember how to play. I just ended up wandering around and getting thrown in the solitary.

Hehe,

 

I was asking because I used the version from post #3...

 

- compressed it with Code3 Cruncher,

- added the title-screen by irgendwer (with Steve McQueen), since I prefered it over the loading screen by Jose (and I did not know then you would use the Steve Mc Queen title in a newer version)...

- asked Homesoft for help, so that you can press any key, the firebutton or just wait after the title screen is displayed to continue loading the game... (irgendwer`s title picture did not allow to continue loading and so I needed a programmer`s help)...

 

Thus, my version does not have Jose`s loading screen, philsan`s title screen nor poison`s title music. But I still like it... ;-)

 

Last not least, I visited the same C64 webpages for manuals and solutions of Fairlight, Total Eclipse and Bobby Bearing. Sometimes even Wikipedia was of great help for the C64 titles regarding manuals, clues, etc.

Well,

 

a 90k ATR image also works fine on a 1050... (or was there another reason for an ED ATR ?)

 

Anyway, here you go, "my" Code3-Cruncher version created from post nr. 3 (GreatEsc.ATR) and mariuszw version with Superpacker from post nr. 8 (GeFinal.ATR)...

 

GreatESC.atr

"my" CC3 version

 

GEFINAL.atr

mariuszw SP version

 

Evil as I am, I added a Basic-off switch to both versions, so there is no need to hold down the Option key. Both images do also contain the manuals and solutions. And errrm, the final version from post nr. 8 uses page 1, so it will most likely not work with HIAS highspeed-OS patch and pokey divisor 0 (try to use my CC3 version instead)...

I played a final version and the graphics were not correct.

 

Thanks for report. Will take a look. Glad you actually completed the game, and (I assume) you found no other issues.

 

Mariusz.
