The Dark Knight [ wip ]

The cdt is the cassette.
Roms can be mounted on rom boards or M4.
Different things.

Here is a turbo-loading tape version. Actually, it's only 30 seconds faster because I've used the standard speed writing, in order to make the loading more "secure".
Here is the code of the new binary loader :

This one is better : I've compressed the 2 loading screens. Loading is now 7mins 18secs long.

Hola Mananuk, thanks for this great game 
I've managed to build a tape version using the good old Oddjob.
You needed to append a LD de,buffer instruction in the binary loader. It is needed by the firmware to store a 2 Kb buffer before calling &BC77.

I had to trim the comments in the Basic loader, so that it doesn't overlap offset 400h in memory, which is the beginning of the game.

150 LOADn$+".scr"
160 RETURNThe loading is quite sluggish. I'll try to speed it up using calls to BC83h/BC98h.
Also, it's a WAV file. CNG has made a tool to convert WAV to CDT (CSW2CDT), but his site is down for the moment.
Now waiting for the sequel 

Thanks for this.
Btw the archive seems broken, at least on my pc 

Hi Jean Marie, Merci pour le fichier, je vais le télécharger sur itchio et vous ajouter aux remerciements, nous l'utiliserons pour créer la version physique

yes https://mananuk.itch.io/dark-knight

[ldaneels]

Is there a minimum to pay to ensure we get a physical edition of the game? I assume there is a cost (production + shipping) to all this for you & I certainly do not want to make you lose money in the process.

I think you are getting confused, I am not the author of the game... this game can be obtained for free on the itch-io page, but if you pay the minimum which is I think 1 euro for the digital version, the author will send you free this new version.
I don't know if the physical edition of the game will come out later, but in any case it will cost much more, logically, you can ask the author on his page, although he also posts here.

[ldaneels]

Ah yes, indeed. Interesting information just the same. 
Hopefully Mananuk will end up releasing a physical edition, the render on his page is just too tempting

Bought it last night !

I must say, its a very impressive game.
I had to watch the YouTube Video however to understand , there is a "double-jump" possible.
Fun to play, and Mananuk even 'upgraded' the
game with Robin   ...
