People were asking how to farm with Geraldo so here it is. Geraldo is worse than Ben but his utility makes up for it in the long run.

Original Video Here(I was not aware that Boar uploaded a video)

In the scenario described, the boss "lych" in Bloons Tower Defense 6 (BTD 6) heals when a tower is sold, and the amount of healing depends on the tier of the tower being sold. Specifically, the heal amount is calculated using the formula:
[ \text{heal} = \text{tiers} \times \text{boss_hp} ]
where:
( \text{tiers} ) is the number of tiers of the tower being sold,
( \text{boss_hp} ) is the boss's health in hit points (HP).
This heal amount, in the context of the game, is then divided by 100 to fit into a 32-bit signed integer variable (final_heal).
Now, the issue of why the heal becomes negative if it exceeds 2.147 billion (the maximum positive value for a 32-bit signed integer) is due to how signed integers are represented in binary.
Explanation:
Signed Integer Representation:
In a 32-bit signed integer, the most significant bit (leftmost bit) is used to represent the sign of the number:
0 for positive numbers,
1 for negative numbers.
Overflow Condition:
When the calculated heal value exceeds ( 2^{31} - 1 ) (which is 2,147,483,647), the integer overflows beyond its maximum positive value.
The overflow happens because the binary representation of the number can no longer fit within the allocated 32 bits for a signed integer, causing it to wrap around.
Resulting Negative Value:
After the overflow, the sign bit (the leftmost bit) in the 32-bit representation becomes 1, indicating a negative number.
The value stored in the integer variable final_heal will be interpreted as a negative number due to the overflow condition.
Example Calculation:
Suppose the boss has 144 million health (144,000,000 HP) and you sell a tower that is 15 tiers.
Calculation: ( \text{heal} = 15 \times 144,000,000 = 2,160,000,000 ).
This heal value exceeds 2,147,483,647 (the maximum for a 32-bit signed integer).
As a result, the integer overflows and final_heal would store a negative value.
Conclusion:
The heal becomes negative after exceeding 2.147 billion due to integer overflow. This happens because the signed 32-bit integer type has a limited range, and when a calculation results in a value larger than its maximum positive representable value, the excess bits overflow into the sign bit, causing the number to be interpreted as negative. In practical terms within the game, this negative value may not directly affect gameplay mechanics but is a consequence of how integer overflow is handled in computer systems.
Written guide because somebody asked
r1: Place free dart
r3: Place Ben (place behind obstacle if available)
r4: Place sub (dart or boomer if you don't have water)
r5-18: Build 2 200 farms then upgrade the first 200 farm to 220 and the second farm to 202, use biohack when necessary
r19: 1 farm tick then sell 202 farm and buy 230 monkey bank
r20-29: Buy 2 200 farms, buy necessary defense and use biohack to defend rounds
r30: Collect bank and upgrade to IMF. After you have gotten 8 farm ticks from the 200 farms upgrade them to 202 and sell them, deposit ~8300 into the IMF Loan
r31-32: Try and stall as much as you can to get the IMF ability
r33: Buy 4 002 discount villages then upgrade your last discount village to 003 and sell the first 2 villages (you can sell 3 if your monkey town can absorb IMF farm). Buy 013 engineer in range of at least 3 of the villages before selling them. Use IMF ability then quickly upgrade your monkey town to 005 monkeyopolis. Get 002 dart for camos. If you have excess cash get a 200 farm.
r34-36: Buy bloon trap and micro it by retargeting the trap(keep doing this until round 40), buy as many 203 farms in range of the monkeyopolis as you can (try to save at least 2.5k going into round 37)
r37: Place 010 glue gunner on last, after trap has captured all black and white bloons place a 004 rubber to gold alchemist also set to last. 003 dart for camo whites. If Ben is using his trojan make sure to sell him on this round
r38: 1 more marketplace, buy 012 glue gunner to make sure you apply "gold" to both ceramic bloons. Get 003 merchantman in range of as many marketplaces as possible
r39: Get 1 more marketplace (not necessary). Buy favored trades before the round ends.

Tier 1: Mintime is 6.15 could have saved a bit of time there.
Tier 2: Super mines is apparently better but didn't know that until after I finished tier 2. I used spike storms + 4 first strikes + crit anti-bloon. I needed to buy tech terror on round 57 and stall rounds to get it. Could have been better but I had one shot. Better strategy would probably use anti+elim/tt but I wanted to save that frame.
Tier 3: Not frame perfect but I was frustrated so took the time anyways. If you want to know how engi instakill works you sacrifice the sentries and they detonate after 2 seconds. Use engi paragon ability and sell the sentry when the boss is vulnerable.
Tier 4: Most clean Engi paragon kill I have ever had even though its not frame perfect
Tier 5: I spent so much time on this tier it was hard to figure out how to add sub paragon to my strategy. I eventually figured out that sub paragon cannot use its nuke ability when vortex is knocked all the way back to the entrance so I had to use its ability for the first hp bar. But using its ability for the first skull allowed one of the missiles to do damage through the shield. Ace paragon was able to kill the second and third skulls so I could sell engi paragon after the third skull.

Improvements: For Tier 1 I can save some more frames but if I want to save more frames on tier 1 I would need to do IMF for 3 spike storms. For Tier 2 I can save some time by using crit AB but I didn't want to do that because I would have one attempt. Tier 3 is just lazy I didn't bother to spend that much time on it so the time is not that great. Same applies to Tier 4. Tier 5 is just awful because lag makes rejuv pain to use. My Tier 5 setup is not that great and can be improved to fit more snipers.

Improvements: Tier 1-Tier 2 can save some frames. My Tier 3 in the video is not my actual Tier 3 because I didn't record it. My actual Tier 3 is around 21.4X seconds. In the real event I should fill every water spot with first strikes to kill Tier 3 faster. Tier 4 can be improved because my micro was terrible. Tier 5 can be improved with more micro and using Geraldo level 20 restock as the paragons barely did any damage.

Improvements: Tier 1 can be improved with faster micro. I could use 032 spikes which is faster but I can't micro fast enough. Tier 2 and Tier 3 can save some frames but its close to perfect. Tier 4 can be improved a lot with better engi and ace micro. Tier 5 is just skill issue I didn't micro ace well and I had 400k spare which I could have invested in more paragon degrees. Also Feedmepi would obviously point out that I don't have Adora but I refuse to use her :)
Improvements:
Tier 1: I decided to do tier 1 kill with 2 first strikes rather than spike storms because it was easier. I can save about half a second if I did that.
Tier 2: I could save a few frames but otherwise t2 was really clean
Tier 3-4: Not frame perfect so I can save a few frames there
Tier 5: I didn't activate some abilities in time and I didn't spam abatteries all over the screen for extra dps. Tier 5 was relatively clean though and it died quickly so I am happy about that.

Tier 1-4 can save some time due to none of them being frame perfect. But I don't want to go insane trying to do that.
Tier 5 was really unoptimized and I should have spent more as I had plenty of cash left over.

Edit: I didn't realize when I entered back into the game that ranked mode is automatically turned off. I already wiped my save unfortunately :(
Notes:
t1: was not frame perfect, but I didn't want to bother trying to get it.
t2: is also not perfect as I could save a few frames but also didn't want to waste too much time. Used sun temple with spike storms which probably wasn't the most efficient but it was interesting at least.
t3: Closest to frame perfect. Used carrier flagship to sell sentries because artic wind for some reason does not sell the sentries
t4: I could have saved some time if I used ace ability on 99 but I didn't want to mess it up as I only had 1 attempt

T2- Scuffed first strike strategy.
T3- Just a simple engi kill
T4- Probably should have had boat paragon, but I went for the cheap way so I lost a few seconds
T5- Did not farm enough money, if I had more efficient farming, I could have saved a lot of time
Round 1 Place a dart on the far left on the leftmost platform and set it to last
Round 3 Place Ben at the start of the round and micro the dart from last to first then to last to pop the blue bloons
Round 4 Place a sub and use Ben's Biohack on the clump of blue bloons
Round 5-14 Place 2 200 farms and upgrade your first farm to 220. Make sure to place your first farm mid-round to get extra $20
Round 15 When you have enough money, place a sniper set to strong and use ben biohack
Round 16 or 17 Upgrade second farm to 202
Round 18 At the start of round 18, let both farms collect one banana and sell you 202 farm for a 230 bank. Buy an engineer at the end of the round to pop the group of green bloons
Round 19 Set engineer to last and upgrade it to 002(This is optional but makes rounds 21-22 really tough)
Round 21 If you delayed upgrading your engi, you can get a farm on this round
Round 22 Use biohack when the bloons start to overwhelm your defense
Round 23-26 Buy a new farm and upgrade it to 220. Use biohack when necessary to deal with bloon rushes
