God Eater Burst

[LunaMoo]

The game might simply be broken.
It uses same engine as GE2 and both games for sure have issues with memory allocation aka they aren't doing it right on ppsspp, GE/GEB was considered playable just like GE2 1.0, however it's unsure if anyone really finished any of those games after last changes affecting them while that change for sure broke GE2 1.4 which was previously playable with workarounds and regressed to unplayable;p.

Overall in that case it's really not something easy to fix, it might still work on some ancient versions, but for anyone that likes GE series and a PC I would recommend just getting it for steam;p, for like 4 days more GE2RB and GER are available in humble bundle(APRIL 2018 HUMBLE MONTHLY, it only lists GE2RB, but GER comes free with it;p) which makes it really cheap and the pc version looks and plays much better than PSP version could ever even with hd texture packs and high render res, it also has very low hardware requirements and works well with keyboard + mouse. The only downside is lack of japanese voices requiring muting all voices to make the game playable(english is terrible and voices doesn't match most characters at all).
