the reason is that the VGA emulator isn't perfect, whereas on the console VGA isn't emulated at all. Especially the missing line-compare register emulation (somewhat hard to fix) causes some problems with vertically scrolling games that have a static status bar somewhere (Jazz JackRabbit, Pinball Dreams 2). Your bug doesn't seem to be in that category though. EGA can be a little problematic because DOSEMU even needs to use CPU emulation to use the planar EGA modes. There's a compile-time constant #define COUNT 150 in src/env/video/instremu.c you could set that to some lower value (10 or maybe even 1). It may or may not help.
