I lol'ed at the quadratic solver mod, also two of those RPGs actually looks awesome. I wonder if I should try them on my 85 at one point. 
The Quadratic solver was something I did based on a suggestion in a ticalc.org discussion. It's in the readme somewhere. For those that don't have an 89 and are curious about it... Yes it is an actual solver, Yes it has storyline, and yes it has a boss battle in the form of a super powered Rhylos. The only way to get the answer is to beat him, and he isn't easy since he could theoretically hit 9999 and has a lot more HP than the FF7:CQ Rhylos. You seriously cannot play the mod unless you beat FF7 and leveled to the point that both Tifa and cloud are maxed out at 9999 health in your save file.
Punisher IV and nPo Vs Hays are pretty much the same game since they both use the PunSyst Engine. The only difference is that nPoVHays uses some of the extended commands that the 86 had, primarily PxlText, so it wouldn't run on an 85. They're also more of a beat em up than an RPG and are really dated by today's standards. RPG wise on the 85, you're much better off with Hiryu's 85 RPG's like conquest or Circle of Light.
