G'day. What a great time to be into the Mamecab scene. First and foremost I must say, fantastic work Sailor for bringing true arcade quality output to the masses!
Couple of questions for the thread :
- Does anybody have a 1:1 pixel and refresh mode for Rtype? - and how did you derive it?
- Are there any pro's and cons in generating modes with LRMC? I have played with it to some degree using the following commandline (lrmc x y refresh -cga -l) where -cga enables 15khz and -l enables low pixel clock generation so as not to double the rez.
Is LRMC the defacto standard, or at least a more than suitable generator? The resason I say this I have attempted generating some modes already present as default in soft15khz and the results are not the same.
- How is this mode derived 401 256 53Hz (Mortal Kombat etc)
? I cannot get anything anywhere near 53hz for that resolution using calculation.
- I'm also getting crap geometry onscreen, a lens type effect where the further you get from the center of the screen, the wider things get...it's like projecting a picture onto a chinese wok. Are there any fundamental differences between a true arcade board and a 15khz Vga output? Can this geometry issue be overcome by tweaked modelines? - or is it simply a chassis/tube issue and replacement is the only solution.
Thanks for the input.
