How To Multiply A Single Value With Vera FX

Hi All, I have being having trouble using the multiplier in VERA FX. I have tried to follow the examples in the manual, tutorial and forum but I have had much luck.

Re: AGI Interpreter February 2025 Update

The DOS and Tandy versions of AGI games are the same files (that's the whole point of an interpreter lol) except for very early versions of Kings Quest.

Re: AGI Interpreter February 2025 Update

However if it would make for a better demo I could swap two and three? Is that your motivation? Well, I put it this way: the AGI support on the CoCo3, they never managed audio support. So it would be nice to see that it is something an 8-bit system could pull off (via delegating to a support chip)....

Re: Sierra AGI Interpreter Update November 2024

The engine is looking close to finished! Well done on the job! Are the views sprites or drawn to the bitmap layer? In my version I was using sprites which presents it's own challenges but I always assumed they'd be faster than a heap of pixel gets/sets. I had sound working in my unfinished implemen...
