Hi there,

While speedrunning the MS-DOS version, and even if I always played this game mute when I was young, I was a bit worried that the fact there wasn't any sound effect during the whole run would make it boring to watch.

So I investigated into the game files and found out that I could activate the sound effects by running the install utility and select soundblaster. But I was quite surprise to notice that the game runs now faster than before! This can be noticed in the starting menu, where the music is played faster.

I tried to switch back to normal, but whatever sound card I select for sound effects (even none), the game still runs faster, while my DOSBox conf didn't change.

Here's what I have in my CPU section: core=auto cputype=auto cycles=fixed 20000 cycleup=10 cycledown=20

I use this for Prince of Persia, but I could set a new FB-only conf if necessary.

So I have two questions: 1 - do you think my game runs at the right speed in my current PB (which I posted in another topic of this forum)? 2 - and if so, do you have an idea about why it runs faster now and what option I should use in order to correct this?

EDIT: so, I checked with the 25th anniversary edition, and indeed the game is running faster than normal. I tried a few changes on the CPU options, no luck.

So I thought that since the changes came from the sound card, it should be related to that. Luckily I saved my old fb folder before launching installer, and I could see the differences in FB.CFG: Previous config: BLASTER = A220 I5 D1 New config: BLASTER = A220 I7 D1

Switching back to I5 slowed down the game to normal speed but also removed the sound effects.

In DOSBox.conf, I have this: [sblaster] sbtype=sb16 sbbase=220 irq=7 dma=1 hdma=5 sbmixer=true oplmode=auto oplemu=default oplrate=44100

Switching irq to 5 sped up the game again while putting back the sound effects. So I reached an impasse there. Do anyone have any idea about how to get sound effects with the right speed?

Hello there,

I'd like to speedrun Wrath of the Black Manta on emulator (plugging my weird/non-standard NES to my PC seems impossible), and thus I wanted to know if an autosplitter existed for this game. I'm not a huge fan of manual split... (I tried to create one myself, but it looks like CheatEngine is making fun of me each time I try to use it)
