Main Information

  • FCEU 0.98.25 (It is no problem in other FCEU)
  • Aims for fastest time
  • Manipulates luck
  • Genre: Platform
  • Takes no damage

Improvement

It is 108 seconds faster than my last run. The key to improvement is the using of tools which can be got after hitting enemy. There are many tools in this game, but most of them will not help us at all. So I only use two of them.

The first tool is the one which can help us walk faster. Its function is to add speed (only X-position). The normal speed is 2.5 pix. We can walk 3.5 pix with this tool. We will not get this tool in stage 5. This tool is no use in stage 3, because we don't need X-speed in stage 3. So I don't manipulate this tool in stages 3&5.

The second tool is the one which can help us hit more HP. Its function is add power (only add the power of the dart). The normal power is 1HP/hit. We can do 2HP/hit with this tool. But it is hard to get this tool. We can only get it in special room (it is not random but regular), and before it, we must get a key. The next problem is that we will level up by getting two of this tool except the first level up (we can level up by only one tool in the first level up). So I only level up once.

How to manipulate luck

There is nothing more to manipulates luck except tools. The memory address 0262 decides which tool we will get. There is only one thing we should take attention to. It is the memory address 0291. This memory address records how many enemies we have killed. We can get a tool only when the value of the memory address 0291 is even. If the value of the memory address 0291 is odd, how ever we manipulate luck, we will not get any tool.


NesVideoAgent: Hi! I am a robot. I took a few screenshots of this movie and placed them here. Oh! I also corrected the ROM name.
  • You indicated Demon Sword (U).nes
  • I updated it to Demon Sword (U) [o1].nes

Bisqwit: Propagating NVA's screenshot edits to forums, and doing some spelling fixes and complimentary proofreading.


Truncated: This seems to desynch on my good [!] ROM. Only the [o1] ROM works. This means that the run cannot be accepted as it is. adelikat has said that he will take a look at the hexability of this, because we would hate to reject a good run.

Looking back, Yunshui's movie was also recorded with [o1], but it synched with [!] anyway.


mmbossman: It appears that xipo's previous submission also used the [o1] dump. As this submission does not break continuity with the prior publications, and attempts to hex it to work with the correct version have failed, I am setting it back to accepted.

However, future attempts will be rejected if they continue to use the overdump. The proper ROM name is "Demon Sword (U) [!].nes", with a checksum of [7e43da13522acdd0d1f170ebdcb24687]
