hail-to-the-ryzen, right, with two lookup tables defined (one for unsigned and the other signed), the need to adjust the 8-bit values (with xor or offsetting by 128) can be avoided and directly looked up as jmash suggested.

I would like to request the conditional removal of a sanity check. That would enable me to post the script that creates the oversize image and makes few necessary changes to the game code I commented out the two lines you mentioned before building r4452, so please give that version a try. Yes, all …

Yesterplay, context into these sanity checks (and others in the CD-DA patch) was to catch and inform users when things have really gone off the rails - for example: bad CD dump, broken/incompatible CUE sheets (which make it beyond the mounting phase), corrupt memory or integer overflows, and the …

I think this is very valuable information both for the preservation of this (increasingly) lost art as well as to gain historic insight into the software protection mechanisms themselves, and how they evolved over time. My understanding is that performing, documenting, and teaching these actions is …

Indeed - the goal was to share @kklobe's work in hopes of progressing an elegant and performant solution; to help the general effort (without any project goals or affiliations in mind). the dual-mapping used in DOSBox-X is better than using MAP_JIT and juggling the w^x protection. Thanks for …

I would suggest copying what DOSBox-X does instead. I understood you weren't happy with what DOSBox-X did from both of your responses: Apparently rather than discussing possible solutions, other people just want to be told what works so they can slap it in their project and take credit for figuring …

Hi almeath, > The patch is meant to also work with standard (SDL1) DOSBox SVN? It's bit-rotten since its last update here, but the work has found a home in DOSBox ECE, DOSBox-X, DOSBox Core, and DOSBox Staging. For SVN, I'd suggest using the latest state of the patch used by ECE - it was last …

What a find, Akuma! Easter eggs like this a rare glimpse into behind the scenes; I find them very interesting 😀 Anyone know of other "communication" type messages in other DOS games? (Feels like this could deserve its own thread!)
