Interesting project.

 

Probably a bit late now, but I noticed that you encoded all levels by hand. The 2600 original calculates them by using a really simple bidirectional LFSR. Have a look disassembly, its in the web.

Hi Ciro!

 

Yes, I saw your youtube comment, thanks ;)

 

You are on now on the waiting list for the 2nd batch of cartridges.

If you want to check out the disk version (also suited for PC emulator), it is available at the TI Games Shelf ( http://tigameshelf.net/asm.htm )

Thanks for pointing that out, I wasn't aware. Find it really astonishing to generate a 255 screen map with 1 byte.

I Didn't look at the 2600 disassembly. I have seen the CV disassembly, but my TI version is pretty much written from scratch (except for tiles&snd).

Ofcourse it is not hard to recognize that it is inspired by the CV version :)

The Pitfall! cartridge for the TI-99/4A is becoming reality!

 

I finished debugging and testing last week and the EPROMS and PCB's for

the first batch are currently in the works.

 

You can see a youtube video of the cartridge version here

Next week I will be contacting the folks that are on the pre-order list for the first batch.

If all works out well, cartridges can be sent out by the end of February :)

This week I received all components required for doing the first batch of cartridges.

So I'm pretty excited about that.

 

Bad news is that I did have some unexpected costs for the first batch, that is the reason I haven't contacted

anyone on the preorder list yet. Trying to keep costs to a minimum, but have to make sure I don't loose too much

money on it.

I'll be contacting the people on the preorder list, once I have most of the carts assembled and know

about the shipping costs.

 

Planning on posting some pictures of the assembled carts soon ;)

Could I get my name on the list for the second batch?

 

Thanks,

tjb

 

Just checked, you are #10 on the first batch icon_wink.gif

 

Did you add me to the list or was I already part of it? Guess I'm getting old, I don't remember...

 

Thanks,

tjb
