Daisuki, Death Crimson Receive Quality-of-Life Patches

Two new quality-of-life patches by romhacker privateye dropped on SegaXtreme earlier this month, this time for Daisuki and Death Crimson.

Released patches for Death Crimson and Daisuki on Saturn that: * disable the white flash triggered by light guns, for the benefit of modern setups that don't require it for hit detection (e.g. MiSTer + GUN4IR or Sinden)* make other improvements to Death Crimson (if I didn't do that, who would?!)

Click here for the Daisuki Flash Removal patch and click here for the Death Crimson Quality-of-Life Improvement patch.

This is our sixth update on privateye’s one-man mission, and it is clear that he will not be stopped until every Saturn title featuring a light-gun has an improvement patch. Check out SHIRO!’s coverage of the others here: House of the Dead, Virtua Cop and Virtua Cop 2; Area 51 and Maximum Force; Hakaider and Scud; Chaos Control and Die Hard Trilogy; and Crypt Killer and Mighty Hits.

Both patches give players the option to remove the “flash” that appears in either game when triggered by the controller. These screen flashes are unnecessary when playing via FPGA emulators like MiSTer or SuperStation One with LCD-compatible light-guns — i.e., GC01, GUN4IR, and Sinden.

The first of the two patches is a flash removal for the dating simulator Daisuki. At first glance, a dating simulator might seem like an odd choice for a quality-of-life patch focused on light-gun games, but Daisuki does feature a Virtua Gun-compatible shooting gallery mini-game. This patch highlights privateye’s “no stone left unturned” approach, if nothing else.

The real star of this pair of patches is the one for the notorious kusogē, Death Crimson.

Death Crimson hardly needs an introduction given it increasingly visible cult status within the retro gaming scene, but most would agree that the game could benefit from some — well, a lot of — improvement patches. In addition to adding the aforementioned “flash removal,” which is optional in this case, privateye’s quality-of-life improvement patch does the following, according to the patch’s SegaXtreme resource page:

  • Increases initial hit points from three to four
  • Increases initial credits to two
    • The retail version normally starts with one credit in Stages one and three, and zero credits in Stage Two
  • Prevents remaining credits from being reduced by ten when facing the first two bosses
  • Improves the Invincibility Code [Enter A+R+Up+Start on either controller]
    • Debug information is no longer displayed.
    • Invincibility is granted against the first two bosses, so now it works everywhere.
    • Invincibility is retained when starting the next stage and returning to the main menu.
  • Adds Unlimited Ammo Code [Enter B+R+Up+Start on either controller]

Privateye seemingly acknowledges that the game remains hard to recommend even with the improvements. He suggests in a reply to his social media post announcing the patches that those interested in Death Crimson as a piece of gaming history and, dare I say, as art should consider watching a playthrough if they are unwilling to suffer.

Here's a neat Death Crimson longplay with insightful text commentary; if you want to passively experience Saturn's finest kusogē instead of suffering through it yourself, look no further! It also demonstrates how the game looks without the white flash (it's still a hot mess, just a bit less so ^^)

Daisuki is a 1997 Japanese-exclusive dating simulator developed by Success Corporation, best known for their long running Cotton franchise, and published by Gaga Communications. The game takes place in 23rd Century. The player, a young cadet transferred to the elite flight school, the “Union Military Academy,” must attempt to balance their training and their dating life.

The Ecole-developed Death Crimson released as a Japanese exclusive in 1996. Death Crimson saw a transformation from “worst game” on the Saturn to “so bad it’s good” over the years, and as tempting as it is to retread that conversation, we instead recommend watching Sega Lord X’s review below.
