summary: How to apply the English patch for Boku no Natsuyasumi 2 on Linux

---
Haven't blogged in awhile, so here’s a quickie. Last week, Hilltop
[released an English patch for Boku no Natsuyasumi
2](https://www.patreon.com/posts/boku-no-2-patch-92070798), which
finally makes the Japan exclusive PS2 game accessible to us English
speaking folks. The README explains how to apply the patch on Windows
or via a web utility. Having never patched an ISO before, I wondered
how it could be done using a native Linux utility instead. Turns out
it's easy to do via the xdelta tool.
First, get xdelta from your distro’s package repository. I use Guix
so I ran `guix shell xdelta` rather than install it because this is a
one-off task.
Then patch the ISO:
```
xdelta3 -d -s Boku2.iso Boku2EnglishPatch1.1.xdelta Boku2-patched.iso
```
Did a quick test in my softmodded PS2 with [GrimDoomer’s modified
OPL](https://www.youtube.com/watch?v=nKoRvWKojz0&t=9s&pp=ygUHb3BsIHBzMg%3D%3D)
so I could easily load it from an SSD in the expansion bay and it
works!!
Of course, I went through all this trouble to play the game because of
[Tim Roger's 6 hour
review](https://www.youtube.com/watch?v=779coR-XPTw&pp=ygUNYWN0aW9uIGJ1dHRvbg%3D%3D)
of the original Boku no Natsuyasumi. Check it out if you haven’t seen
it.
