(2/2) CHANGELOG

• Refactor background sound modulation in Galaxian which sounds very close now to what's heard on the real PCB

-Use of the VCO modulation for Kings and Balloons was muted by the original author (background during gameplay was silent). After verification this game is supposed to use the same modulation sweeping as Galaxian except it's not ramping up with time. Correct behaviour is now restored

• Votrax chip added to Qbert core which can now talk

MSX core has been updated to the latest One Chip MSX core (3.9.2) on MiST and Sidi. :ablobcatbongo: . It's a real step forward 😃 (1/2)

==== MSX_260131.rbf ====

- Modules updated to v3.9.2 including the latest KdL Github fixes up to 25th of november 2025. Details available here : https://github.com/gnogni/ocm-pld-dev/blob/master/history.txt

- Replaced the YM2413 (OPLL) sound module core with IKAOPLL which is a cycle accurate version of the chip for better sound accuracy matching the real hardware.

#MiSTBoard #FPGA #Arcade

(2/2)

• No need of separate cores for each game (just blueprnt.rbf and one mra per game)

• DIP switches fully implemented for the 3 games

• Improved CRT picture centering (previously even using the CRT adjustments in the OSD, the bottom part of the vertical picture was always truncated)

• Improved clock parameters for the OSD. With previous version in-game picture was okay but the OSD appeared wobbly when pressing F12. Now everything is nice and clean
