Can't load IPF of Lotus Esprit in 4.9.0 & 4.9.1b4?

BarryB · 13 January 2022, 20:37

Seems Lotus Esprit IPF #0774 doesn't want to load anymore in 4.9.0 x64 and 4.9.1b4 x64?

Using Quickstart A500 1.3 (most common) config and it sticks on track 1, Shaun Southern MFM track format. If I go back to an older 4.2.1 build it loads.

Strangely, the French IPF #2848 does load in 4.9.0 x64 & 4.9.1b4 x64?

Anyone else seen this?

Yes, same behavior here in 4.9.1b4 x64.
It stops on track 01 and just hangs there.

Fixed very quickly. MSBSYNC emulation broke this as a side-effect.

Game waits for index pulse in 4us mode (it gets set back to 2us when game starts loading) and if inserted disk is normal 2us MFM, index might not be detected correctly.

Yes, ejecting the disk and re-inserting it two or three times seems to get it loading and confirms your findings

Just tried 4.9.1b5 x64 which has fixed the problem
