Re: WIP: Reversi (was Othello)

> Perhaps we can fit eight 4K games within 32K EPROM, of > which each set of two games is selectable with DIP switches Why DIP switches? 32K can be addressed from the CPU all in a row, no need to bank switch. You need a 8-games menu, and you don't even need to do eight 4K games, you can even mix gam...

Re: Text/Graphic adventures

I recently thought ot text adventures too, not sure how many people would got interest into them it they had no appealing graphics. As for the graphics, I fear that the limits of the TMS9928 would be a problem to get nice "bitmap-style" pictures. :-/ I dont think there's need of a rasterline counter...

Re: WIP: Reversi (was Othello)

Well no code yet, I'm into writing and translating the tutorial about the composite video output mod. I've been contacted by a friend programmer, who's willing to also code games for the CV. He's looking for "Appendix E" of the "Programming guide" to the TMS9918. There's a guy who owns the book, (it...

Hi man, have you stopped developing the game? Any good news?

Re: Laser 2001 & Salora Manager - official thread

I think Giovanni Ortu's "CvTape" tool would do good if only it was "modded" in order to be compatible with Laser 2001 tape format.

But an easy way to "dump" the ROM from tape could be a "LLIST" of the raw data bytes to a parallel printer.

Re: WIP: Reversi (was Othello)

Ooooh I see, now I understand what those label$ stand for :-)

As for the ORG in the middle of the ASM code, I was aware of that. It's definately a clever way to code. :-)

Re: Laser 2001 & Salora Manager - official thread

I made a short BASIC listing to disassemble the "BIOS", nothing special, just a for-next cycle with "print chr$(peek(x))" in it. I peeked around 1000 locations from 49152 onwards, and found out the BASIC interpreter ROM, so I suppose it's there for the upper 16K from $c000 to $ffff Peeking locations...

Re: Laser 2001 & Salora Manager - official thread

Since I got an addit. boxed joystick for the Salora Manager, I decided to test it on the console today. I tried the "Astro Pinball" game, which has an odd behaviour on the Salora Manager: the left and right buttons are SWAPPED (you control the left flipper with the right button, and vice versa). I t...
