For making Africa less like otl, you could glom Sudan onto fascist Egypt. Then the south could be in a perpetual state of unrest as per otl. Rwanda and Burundi maybe get bundled together and have a slightly less sad history?
DRoCongo could be split up, as nearly happened iirc, and Nigeria as well. Megasouthafrica could have steamrolled mineral rich Botswana, if the UN didn't strongly step in. To make the map look even less like ours, and reduce the number of countries you need to keep track of, you could have the British and French each clumping into federations.
Depending on the backstory, Jordan could be part of Arabia or Iraq or even Syria, if the Hashemites wound up keeping any of the respective crowns. Since I've been told Egypt is fascist having one of Syria, Iraq, and Arabia be democratic, one socialist, and one 'other' (theocracy, anarcho-syndicatialist commune, what have you) could create a fun! dynamic.
I'm thinking I'm going to use some of this. I thought about split Nigeria, but decided a united one would be a more interesting player in the Non-Aligned Movement (which is almost entirely an African thing TTL; Indonesia, New Zealand and a lot of smaller Caribbean and Latin American countries are either members or pay it lip service.) I thought of a few more changes myself.
I may split the Congo if I can find a good map.
South Africa does own Botswana, and the occupation of it isn't pretty. South Africa isn't directly in the Axis, but they still keep the UN out of the region and that's good enough for the Germans. Angola, Rhodesia and Mozambique are all very, very nasty apartheid states that are about as progressive on race as Germany, if not worse, and South Africa uses them to bully countries it doesn't want to be caught interfering with itself. Zambia, under the rule of a nationalist but pragmatic President-for-life, plays along with the South African gang to avoid getting trodden on. Malawi is a very, very, very paranoid country, but they haven't been conquered yet, so they must be doing something right.
Tanzania broke back up after a few years, and Zanzibar is both pretty prosperous and one of the few genuine democracies in Africa.
The Federal Republic of Senegambia is a thing and is doing just fine, thank you.
The Central African Empire is run by Bokassa I, who is getting on years, but has a lot more military success to back up his claim to being Napoleon's successor. He was armed by the British and French early on as one of the few African rulers willing to take an explicitly anti-Axis line in the mid-70s, but lately has tried to strengthen the Non-Aligned Movement. He managed to conquer Chad and later Cameroon as they fell into civil war, and is getting ready to pass the throne to his son. Central Africa is pretty well developed, considering, and is the biggest sub-Saharan African power after South Africa and Ethiopia.

Each Middle East / North African state from Morocco to Iraq is under its own kind of nationalist government, all in the Axis but all pretty opposed to each other and willing to fight:
- Morocco is a Spanish puppet whose Sultan spends as much time in Madrid as he does in Rabat, and he even has his own Moroccan Falange.
- Algeria is an orthodox fascist state with an utter hatred of the French. Very enthusiastic German allies, and have nasty race laws against the Tuareg population.
- Tunisia's "nationalist" government is a joke, with its Presidents willingly selling out their country to Italian interests for a hefty sum. Basically an appendage of the Italian empire.
- Egypt's authoritarian but pro-UN monarchy was deposed just before the Suez Crisis. The local fascists are Egyptian nationalists, not pan-Arabists, which infuriates the Syrians.
- Israel and Lebanon are very paranoid but free UN-aligned democracies. Considering the Egyptian government, they won't give up the Sinai in a million years.
- The Kingdom of Arabia is an absolute monarchy, like OTL Saudi Arabia but less aggressively religious. They don't like the Germans, but they pay better.
- Yemen and Oman are dictatorships without much in the way of ideology that have bounced around between the UN and Axis camps over the decades.
- Syria...er, excuse me, the United Arab Republic, owns Jordan. The Arab pan-nationalists in the Arab Party are frustrated with the rest of the region's hesitance to get on board, but anyone seeing how the Syrians run Jordan wouldn't be very enthusiastic.
- Iraq is run by the Ba'athist Party, also Arab pan-national fascists but with some quasi-socialist tinges; the Strasser to Syria's Hitler. Mainly, they just think they should lead the Arab project instead of the Syrians. They fight constantly, and Syria usually wins.
How does the British Commonwealth look ? What countries still maintain Elisabeth II as a crowned head ? Does Canada have the Maple leaf or the old dominion flag ?
I don't have a complete list of Commonwealth countries, but Newfoundland, Belize, the Bahamas and Malta all have devolved parliaments on the Northern Irish model. Other than OTL, Sri Lanka and Malaysia are Commonwealth realms. Canada flies the Maple Leaf, and since the British worked pretty hard at keeping Newfoundland are actually less friendly with them than OTL. They aren't a republic (yet), but republicans have been getting farther and farther in the Liberal Party.
