Need help with FFD2 (CHROUT)
Has anyone ever encountered a situation where sending a value to FFD2 results in the wrong value being sent and with that wrong value returning in the Accumulator? If I do a READST immediately afterwards it returns $00

have you traced it to see if that is what actually happens? sounds like the problem is unrelated to ffd2
I'm just a Software Guy who has no Idea how the Hardware works. Don't listen to me.
Re: Need help with FFD2 (CHROUT)
What device are you sending it to?

Re: Need help with FFD2 (CHROUT)
Thank you for the tip. Stepping through FFD2 I found it is using $FA and I happen to use it too. So I adjusted my prg not to use FA and now it works!!!groepaz wrote:have you traced it to see if that is what actually happens? sounds like the problem is unrelated to ffd2
