As the replies above yours indicate- an accurate Tandy/PCjr patch calibrated from real machines is not yet ready. The best one currently available is the PCjr patch by NRS which can be found on page 35. But while we're at it, since you've been submitting composite CGA shots on MobyGames, I'd urge you to use the latest accurate patch instead of what's in DOSBox SVN. ;)

I just started using that patch you suggested me.

Here is reenigne's improved composite CGA patch updated for current DOSBox SVN (as of r4115).
Refreshers: F12 toggles composite on/off/auto; Ctrl+Alt+F11 cycles through settings to change (CGA model, hue, saturation, contrast, brightness, sharpness); F11/Alt+F11 modify the current setting. You might need to generate a new keymapper file while in machine=cga.

dosbox-r4115-composite-hires.diff

dosbox-r4115-composite-hires.zip

Since r4095, DOSBox's opengl output can handle >8 bpp inputs, so the emulated composite screen can be aspect-corrected properly now. (The above build also has the enhanced normal scalers, so you can set e.g. "scaler=normal2x forced" and it'll actually have an effect in this mode.)

The color-depth issue was the only disadvantage of this patch vs. DOSBox's existing one. Since that is now solved, I see no real reason why this shouldn't be committed to trunk. ;)

I don't see Tandy/PCjr composite support though. I would say that should be added before "committing to trunk".

That'd be nice. We'd still need the chroma_multiplexer arrays for those machines, so Trixter/reenigne are welcome to indicate here whether they'd appreciate more prodding in the matter. :D

I consider myself appropriately prodded. Life is and has been crazy and hectic this past month, but I'll stick another reminder in the calendar for July.
