This is Maxim all bosses run of Castlevania: Harmony of Dissonance. I performed a drastic reconstruction of the route and saved McBobX's current run by a lot of frames with that (due to the difference of emulators, we can't compare their movie lengths exactly though).


  • Emulator used: BizHawk 1.11.6.
  • Starts from SRAM.
  • Uses warps.
  • Aims for fastest time.
  • Aims to defeat all bosses.
  • Abuses glitches.

About the run

Definition of the goal

To set flags of destruction of all bosses ($000358, EWRAM domain). We can make a judgement of it with the hatchway to Dracula Wraith's room.

Emulator and core selection

I used BizHawk with mGBA core instead of common VBA to make this run. I think VBA is also okay for now, but BizHawk is seems to be better than VBA in terms of future TASing. That's why I chose BizHawk. As you know, BizHawk supports two cores for GBA emulation: VBA-next and mGBA. It's embarrassing, but I really don't know which core is suitable for CVHoD, so I selected the new one (mGBA) for the present.

Making the SRAM

Due to the change of emulator, there's need to make a SRAM to start this run. I made a semi-TAS movie at first.

Lua scripts used

I edited Robert_Ordis's lua scripts so as to be available on BizHawk environment and integrated some further functions. It can be downloaded here. The original scripts can be found in his submission.

History of the branch

After the publication of current run, several works have been done in Japanese community (nicovideo). However, most works have not been reported to oversea communities, including TASVideos, I guess. So I'll show history about this "Maxim, all bosses" branch including in-bounds run as reference.

Yuzuhara_3's "Maxim, in-bounds" in 11:39.95 (released on 2011/08/11)

It improves Comicalflop & zggzdydp's initial in-bounds run by 2037 frames. He succeeded to construct the new route which doesn't require door-warp glitch.

Yuzuhara_3's "Maxim, in-bounds" in 11:12.02 (released on 2012/12/25)

Sadly, he deleted the two videos, but they are still available as a comparison video encoded by ISMin.

Tarion's "Maxim, all bosses" in 07:09.08 (released on 2014/03/14)

It improves McBobX's current run by 1175 frames.

Tarion's "Maxim, all bosses" in 07:02.70 (released on 2014/04/04)

This run had been a substantial record of the branch in nicovideo for two years.

My suggestion of new route for "Maxim, all bosses" (released on 2016/01/23)

I had assumed a new route since the end of 2015. Although there are several differences between this submission and the suggestion. This saves Tarion's run by 1 minute.

Tarion's incompleted WIP for "Maxim, all bosses" in 06:37.33? (released on 2016/01/26)

Then he released this video 3 days later. It seems that his run had been stagnant for a year. His strategies helped the run a lot.

Thanks to

Robert_Ordis and gocha

They made useful Lua scripts for CVHoD TASing.

Tarion and Yuzuhara_3

They showed very optimized strategies on every boss battle.

All CVHoD TASers

Samsara: Yessssssss. Judging!
Samsara: Accepting as an improvement to the published run.
