Phantasy Star II Modernization

Hack of Phantasy Star II


The purpose of this hack is to mitigate many of the flaws of Phantasy Star II in order to create an overall play experience more similar to that of Phantasy Star IV. This means decreasing the amount of level and money grinding, increasing the number of references to other games in the series, script improvement, bug fixing, and more.

Major changes include: character niches and specialties are enhanced, technique arsenals are improved and mastered more speedily, shop and treasure chest contents are streamlined, characters join with better equipment, useless items are retired in favor of better ones, enemy names are expanded and made more consistent with the other games, etc.

We are currently on Version 4.1, the seventh release of this hack. Version 4.0 was a complete rebuild from the ground up using the Phantasy Star II Disassembly document by lory1990, available on this site. 4.1 only addresses a few small issues from 4.0. Please see the readme for details, and thank you to everyone who tries the hack!

A few suggestions

Reviewed By: RainDrew on 27 Feb 2021

First of all - great work on continued improvement of the hack!

I remember playing earlier versions - swords were a better option for Rolf in comparison to the equal quality knives, however, this time around swords do about the same damage as the equal dagger hit (cer dagger vs cer sword for example) is this by design or an oversight?

While some techs got their cost decreased and potency improved, especially healing, other got increased without boosting their potency, Zan for example. Wat does barely more than foi while costing 4 tp.

Before i could patch the “easy mode” hack on top of this for a x4 exp/mes, but now this doesn’t work, probably due to new code. Would be nice to have x3 and x4 versions of the game added to the archive.

Fast walking hack should probably added by default, unless it can be patched on top without issues.

Everything else about the hack is great: new dialogues, gear rebalance, etc.

Version 4.0 Recommended - Yes
