Super Robot Wars/BX/Info Dump
The battle record for acquiring certain amounts of money seems to take into account the value of pre-existing upgrade bars. So you can get the 30 million one and then start your next playthrough with less than that (BX's money carryover is always 100%, even on playthrough 1).
15-upgrade mode is unlocked on the 4th playthrough. The amount increased on HP, EN, Armor, Mobility, and Targetting is the same for the extra 5 blocks. For attack power, it's 1250, 1350, and 1400 for the 1250, 1400, and 1600 upgrade tiers, respectively.
Certain secrets require the "X vs Y" condition to be done twice, because the game doesn't prioritize the secret-triggering dialogue over a regular pre-battle conversation. For Hy, you have to fight him twice with Jojo in stages 13 and 24. For Todd, Slarzen has to fight him twice in stage 24. For Belzeb, Maria has to fight him twice in 22, Jin has to fight Black Taida twice in stage 34 if and only if you've combined into God Raijin-oh before triggering the conversation. If you haven't combined, you only need the one conversation. In addition, Maria vs Belzeb in 34 must be done before he hits 70% or less HP. And in stage 33, Versal Knight vs Neo Black Dragon must be done twice.
