oli1980, that build you picked is a fork. Can you try ripsaw8080's suggestion using an SVN build, which is the successor to the original DosBox version v0.74-3 you mentioned initially using? Filename is DOSBox r4471.7z , here: https://yesterplay.net/dosboxece/ EDIT: Sorry, make that DOSBox r4473.7z

DOSBox 0.74.3 and SVN should also be considered: - 0.74.x is extensively tested and still drives many GoG releases to this day. - SVN continues to be maintained with very careful updates (often to critical core emulation areas). - SVN's sharp GLShader lets one dial in exact integer scaling by …

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.

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 …

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 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 …
