https://tombasoft.com/en/devlog/ The development diary of Tombatossals Softworks: The Penumbra Directive, El Mister, BLACK WIRE and the Castalia systems. en © Tombatossals Softworks LLC Mon, 13 Jul 2026 12:00:00 GMT https://tombasoft.com/en/devlog/ganar-el-tiroteo-perder-el-caso/ https://tombasoft.com/en/devlog/ganar-el-tiroteo-perder-el-caso/ Mon, 13 Jul 2026 12:00:00 GMT BLACK WIRE Black Wire’s Director’s Cut. Why the scoreboard stopped being a score and became an eight-count indictment, how the Wire Bench lets you fabricate evidence without knowing it, and why a solver proves every operation winnable on every build. https://tombasoft.com/en/devlog/una-fuente-trabaja-para-otro/ https://tombasoft.com/en/devlog/una-fuente-trabaja-para-otro/ Sun, 12 Jul 2026 12:00:00 GMT PENUMBRA The Penumbra Directive. Why we compromise your intelligence from day one with a different mole every run, and how a causality timeline lets you trace any crisis back to the decision that caused it. https://tombasoft.com/en/devlog/dac-en-el-puerto-de-impresora/ https://tombasoft.com/en/devlog/dac-en-el-puerto-de-impresora/ Fri, 10 Jul 2026 12:00:00 GMT CASTALIA 92 Devlog v0.51. Covox Speech Thing and Disney Sound Source in Castalia 92: digital audio over the parallel port, paced by the PIT, and why we never probe for them. https://tombasoft.com/en/devlog/reconstruir-un-kernel-por-tres-lineas/ https://tombasoft.com/en/devlog/reconstruir-un-kernel-por-tres-lineas/ Sun, 05 Jul 2026 12:00:00 GMT CASTALIA DOS The stock FreeDOS KERNEL.SYS prints its banner from a packed image whose strings cannot be edited. For a 386 to boot saying CASTALIA DOS — and nothing else — we had to recompile the kernel from source. https://tombasoft.com/en/devlog/recursion-sin-pila/ https://tombasoft.com/en/devlog/recursion-sin-pila/ Sun, 28 Jun 2026 12:00:00 GMT CHUMOS AmigaOS gives each process ~4 KB of stack, and copying a folder tree is recursive by nature. Why ChumOS copies single files with an 8 KB buffer and leaves recursive copy unimplemented, instead of pretending it works. https://tombasoft.com/en/devlog/ocho-puertas-una-conjetura/ https://tombasoft.com/en/devlog/ocho-puertas-una-conjetura/ Sat, 20 Jun 2026 12:00:00 GMT CASTALIA DOS Why Castalia DOS greets you with a menu of eight memory configurations instead of one clever autodetect. Spoiler: because DOS games do not forgive. https://tombasoft.com/en/devlog/capturas-de-una-maquina-que-no-puede/ https://tombasoft.com/en/devlog/capturas-de-una-maquina-que-no-puede/ Fri, 05 Jun 2026 12:00:00 GMT CASTALIA 92 A real-mode 386 has no screenshot button. How CI boots the compiled .EXE in DOSBox over Xvfb and grabs the screen with ImageMagick: the images come from the binary that ships, not from a reimplementation. https://tombasoft.com/en/devlog/cero-por-ciento-en-reposo/ https://tombasoft.com/en/devlog/cero-por-ciento-en-reposo/ Sat, 30 May 2026 12:00:00 GMT CHUMOS Nothing in ChumOS polls. Every event arrives as a signal into a single Wait(), and the whole screen composes and blits in one beam-synced operation. Here is how. https://tombasoft.com/en/devlog/componer-en-32-presentar-en-8/ https://tombasoft.com/en/devlog/componer-en-32-presentar-en-8/ Wed, 22 Apr 2026 12:00:00 GMT CASTALIAOS 98 PE The entire CastaliaOS 98 PE interface composes into a 32-bit XRGB back buffer and presents to 8- or 16-bit hardware as dirty rectangles. No dithering, no palette search, no alpha.
