SushiSwap - Inner workings?

I've been trying out in the past few days SushiSwap and lately SashimiSwap Contracts & Frontend and while I'm still getting familiar with the code. It turned out to be quite a challenge to make it work... Something is definitely missing since there are no tokens being minted after LP Deposits 😂.

Here are the steps that I did so far: Tested on KOVAN Network

1. Created SushiToken
2. Created MasterChef
3. Transferred Ownership from SushiToken to MasterChef
4. Created 3 LP Pairs on Uniswap (Sushi-WETH/Mock-WETH/Sushi-Mock).
5. Used Masterchef.add(allocPoints, lpAddress, true) for all 3 pools.
6. Matched SushiToken, MasterChef, and LP addresses on the FrontEnd.
7. Approved & Deposited the LP on the FrontEnd Farm Deposit Section.
8. Should see tokens being minted on the left side but they stay at 0.00.....

This is what I got so far regarding the migration. I added MockERC20 which is actually a clone of SashimiToken and WETH9 is a WETH Clone. Here comes some code:

Frontend Changes:

1. Commented out 3 lines to connect to exclusively to Kovan. https://github.com/SashimiProject/sashimiswap/blob/master/frontend/src/utils/getEthChainInfo.ts#L7-L9
2. Updated the constants.js file to match all LP's and Token Addresses. https://github.com/SashimiProject/sashimiswap/blob/master/frontend/src/sushi/lib/constants.js

UPDATE 25 Sep:Found out that Uniswap uses different versions for the Factories and Interfaces which are deployed mostly on Solidity ^0.5.0 and some are on ^0.6.0 or =0.6.6. After updating to make them all to pragma solidity =0.6.6; The pools give accSushiPerShare and we can see RewardDebt but still no yield is being generated.

UPDATE 30 Sep: Still can't figure out what I'm doing wrong. This is the repo that I managed to put together so far. The only step that does not work is the actual token minting after you deposit the UniswapV2 Pair LP.
