MAME 2003-Plus has a couple of mysterious options called crosshair_enable (“enabled”) and crosshair_appearance (“simple”), yet nothing renders on a game like Seawolf and Seawolf2. Until you go searching through the source code, the appearance option can also be set to “enhanced”.
The draw_gfx function seems to do internal rendering, that is, it does not make use of any external artwork / crosshairs as you might use from Mr. Do’s Artwork.
What gives? Is this is a fruitless endeavor to have a visible crosshair from the latest RetroArch on a Pi 400 running Seawolf? I’m just looking for a Nay / Yay, and if a Yay, a “how to”, thanks.
