INFOCOM series on CoCo-VGA for DRAGON64
Posted: Thu May 03, 2018 11:16 pm
Hi,
I have isolated this message from the previous announcement of the port of the 25 adventures games from INFOCOM, because this one implies
the use of an extra module attached to our Dragon (this one lies inside the case!), its name is CoCo-VGA and you can learn a lot about it here:
http://www.cocovga.com/
One of the advantages of having that module is that we can set it to work at 64 columns by 32 lines in mode text, enabling lowercase too!
The changes to the 'engine' I had converted have been possible thanks to Ed Snider who, very kindly, has shared with me the mods he did
on the CoCo version, thanks a lot!!
You will notice that in the extra disk "ENGINE.VDK" there are two files instead of just one.
- ENG04V32.BIN is for normal use 32 chars x 16 lines as usual
- ENG04V64.BIN is for CoCo-VGA users and will switch the module to mode 64x32 with lowercase
Keep into account that right now this works flawlessly with TANO computers (NTSC)
I know that Brendan Donahe is working hard to fine tune it for the Dragon PAL too, so it is just a question of waiting a bit to test ...
Just a proof that it works till the end, I played "The Lurking Horror" (cheating with a walkthrough) but needed to test it! cheers
